Create a chic, stylish character ILLUSTRATION of a handsome young man for a premium video production company brand campaign, based on the person in the photo. This is refined illustration art, NOT a photograph.

ART STYLE - refined and delicate:
Elegant modern editorial fashion illustration. FINE, THIN, delicate linework - crisp and light, never thick or heavy outlines. Minimal, sophisticated cel shading with soft subtle shadow shapes and clean flat color areas. Sleek, polished, high-fashion magazine illustration aesthetic. Restrained and tasteful, not cartoonish or comic-book heavy. Clearly drawn illustration, no photographic texture.

CHARACTER - handsome and refined:
A very good-looking, stylish young Japanese man in his late twenties. Handsome idealized features: sharp defined jawline, elegant slim face, well-shaped expressive eyes, refined nose, clean sophisticated look. Tall and slim with elegant fashionable proportions. Charismatic and effortlessly cool - like a young creative director featured in a fashion magazine.
Carry over his signature trait: naturally wavy, curly, voluminous black hair with beautiful movement, styled attractively.

EXPRESSION:
A confident, charming, relaxed smile. Bright lively eyes. Cool and stylish energy, warm but sophisticated - not goofy or overly cheerful.

POSE AND STYLING:
Upper body, standing elegantly, body slightly angled, face toward camera, one hand relaxed in his pocket. Not holding anything.
Wearing a beautifully tailored, well-fitted modern black jacket over a plain fine tee. Sharp, fashionable, sophisticated creative-industry styling. No logos, no brand marks, no text on the clothing.

COLOR AND COMPOSITION:
Bold vivid saturated yellow flat background. Black and white as supporting contrast colors. Elegant graphic contrast. Character centered, clean poster composition with generous negative space.

Sophisticated, stylish, vibrant mood. No text, no logo, no watermark, no signature.

Create a 15-second 16:9 photorealistic, cinematic, high-energy brand promotion film for a YouTube channel management company. Live-action realism throughout, dynamic camera work, stylish premium commercial cinematography, shot on cinema camera with shallow depth of field and natural film grain. The video must be in constant motion from the very first frame - never open on a static still photo.

Two characters appear throughout: a man (from reference image 1) and his dog (from reference image 2), who are inseparable companions and appear together in nearly every scene, always close to each other.

Man: preserve his exact facial identity, real skin texture, natural wavy dark hair, and body proportions in every shot - always immediately recognizable as the same real person from reference image 1. He wears a sharp black jacket. Energetic, genuinely smiling, full of enthusiasm and joy. Do not show extreme close-ups of his face - keep him in medium or wide shots throughout.

Dog: preserve the dog's exact appearance from reference image 2 - the same black-and-white long-haired border-collie-type coat pattern (black head with a white blaze down the face, white chest and legs, bushy black-and-white tail), same size and proportions, in every shot. The dog is playful, energetic, always moving with him, trotting alongside, looking up at him.

0.0-1.5s
The video opens already in motion: the man and his dog walking together side by side into frame with confident energy, camera tracking alongside them in a dynamic dolly move, dark studio space with bold vivid yellow accent lighting sweeping across the frame.
Camera moves fluidly, never static, never a frozen shot.

1.5-3.0s
The dog trots ahead happily and looks back at him; he laughs and jogs a couple of steps to catch up, reaching down to ruffle the dog's fur.
Camera arcs low around the dog then rises to a medium shot of both of them together.
Warm yellow rim lighting, shallow depth of field, subtle film grain.

3.0-4.5s
He sits at a sleek editing desk, hands moving fast and precisely across the keyboard, laughing with focus. The dog sits loyally right beside his chair, then hops up with front paws on the desk edge watching the screen with him.
Dynamic low sweeping camera arc around the desk.
The monitor in front of him glows with abstract flowing color panels and waveform shapes - no readable text or letters anywhere on the screen.

4.5-6.0s
Camera swoops rapidly toward the glowing screen. The screen surface ripples like water and BURSTS open.
The dog leaps through first, bounding out of the screen into the real room mid-air, joyful and wild, followed immediately by the man leaping through right behind, backlit by a blinding burst of warm yellow light and glowing floating particles that look like sparks of ideas.
Motion blur, dynamic low-angle camera, confetti-like light particles scattering.

6.0-7.5s
More bursts of energy erupt from the rippling screen behind them: a fox darting past, a large bird taking flight, more glowing particles, all fully photorealistic.
The man and his dog run forward together through the burst, side by side, full of joy.
Camera does a fast dynamic dolly-out revealing the whole burst of energy filling the room. Bold yellow light floods the scene.

7.5-9.0s
He stands with arms thrown open, head tilted back laughing, the dog leaping up excitedly beside him, both catching the glowing particles around them, backlit with dramatic yellow rim light.
Low-angle dynamic camera.

9.0-10.5s
Camera flies fast through the swirl of glowing particles, the man and his dog running through it together, blurred flashes of real environments passing by - a film set, a cityscape, a stage - all photorealistic, seamlessly connected by fast whip-pan camera motion.
No text or UI panels of any kind visible.

10.5-12.0s
A team of people working together at a row of glowing desks, high-fiving, laughing, dynamic energy, camera arcs around them in one continuous fluid move. The dog trots happily between the desks, tail wagging, everyone reaching down to pet it as it passes.
Warm yellow accent lighting mixed with cool screen glow.

12.0-13.5s
He walks straight toward camera with powerful confident strides, jacket moving with him, the dog trotting right at his side matching his pace. Dynamic low tracking shot, glowing particles and light streaks trailing past them. Pacing and camera speed both accelerate.

13.5-15.0s
Final hero shot. He stands centered in a medium shot, arms open wide, beaming with genuine joy, the dog sitting proudly right beside his leg looking up at him.
Camera settles into a clean steady medium shot, both of them clearly visible.
Background simplifies into a clean bold vivid yellow field with soft light rays.
The final logo appears cleanly centered in solid black, positioned above them with no overlap: the single English word YANAGIMATSU, spelled exactly Y-A-N-A-G-I-M-A-T-S-U, in one clean bold sans-serif line. This is the ONLY text in the entire video - render it sharply and correctly, in simple flat typography with no extra decoration.
Freeze on the final beat.

Overall Style
Premium live-action commercial cinematography, photorealistic, dynamic and stylish, fashion-commercial lighting. Bold vivid yellow as the dominant accent color against black and deep shadow, warm rim lighting, cool screen glow as secondary light. Constant fluid dynamic camera movement - dolly, push-in, arc, whip-pan, low-angle - never a static locked shot, never a still photo. Realistic motion blur, natural film grain, cinematic color grading. Joyful, energetic, exciting, premium creative-agency mood throughout. The man and his dog are inseparable companions and should share the frame together as much as possible.
Screens shown in the video display only abstract glowing shapes, color panels, waveforms and light - never any readable text, letters, numbers, logos, or interface labels of any kind, and never any real brand's logo or trademark.
The man must remain clearly recognizable as the same real person from reference image 1, and the dog must remain clearly recognizable as the same dog from reference image 2, in every shot.

Avoid
No static opening shot, no still-photo freeze at the start, no illustration style, no cartoon, no 2D flat design, no anime, no face drift on the man, no identity drift on the dog, no character replacement, no extra limbs, no distorted hands or paws, no unstable proportions, no chaotic unreadable camera shake, no low-quality CGI, no watermark, no gloomy or serious mood, no extreme close-up shots of the man's face. Absolutely no letters, words, digits, numbers, captions, UI labels, or any text of any kind anywhere in the video except the single final logo word. No real brand logos or trademarks anywhere. No Japanese text or Japanese characters anywhere in frame.

4.0-6.0s
They both turn to face camera together, the man standing with the dog sitting beside his leg looking up at him, backlit with dramatic yellow rim light. Camera does a slow steady push-in.

6.0-8.0s

Two lines of text fade in cleanly, stacked vertically above them, in solid black, sharp and perfectly legible:
Line 1, larger, in Japanese: 相棒と、いつも一緒に。
Line 2, smaller, in English below it: YANAGIMATSU
Render both lines of text with completely accurate spelling and correct Japanese characters - no distorted, garbled, or invented characters.

Freeze on the final beat with both lines of text fully visible and sharp.

Overall Style
