Yamaha R15 V4 — Premium Bike Portrait

Create a highly photorealistic vertical lifestyle photograph of a young South Asian man sitting casually on a Yamaha R15 V4 motorcycle in an outdoor park.

Preserve the man's facial identity, natural facial structure, hairstyle, skin tone and overall appearance from the reference image. Keep his face realistic and natural.

He is sitting comfortably on the motorcycle with a relaxed, confident pose. He is wearing a black T-shirt with the word “KING” printed clearly in red on the chest, relaxed-fit brown cargo trousers, white sneakers with subtle blue and red detailing, and a smartwatch on his wrist.

The motorcycle is a Yamaha R15 V4 in a striking white, blue and black color scheme, with realistic Yamaha and R15 V4 branding, detailed fairings, sporty headlights, alloy wheels, disc brakes and authentic motorcycle proportions.

The setting is a peaceful green outdoor park filled with large mature trees, dense green foliage, grass and a natural dirt pathway. The motorcycle is parked beneath a large tree. Include realistic sunlight filtering through the leaves, natural shadows and soft background bokeh.

Composition should closely match the reference: full motorcycle visible, subject sitting naturally on the bike, plenty of environmental background, vertical portrait framing.

Ultra-photorealistic photography, realistic skin texture, detailed clothing fabric, accurate motorcycle details, natural colors, DSLR-quality image, shallow depth of field, cinematic but realistic lighting, sharp subject, 8K Ultra HD.

Vertical 9:16 aspect ratio. No extra people, no unnecessary text, no watermark.
