Golden Grassland Mountain Bike Fashion Portrait

Using the uploaded photo, create a photorealistic full-body outdoor fashion portrait of the same person standing beside a black hardtail mountain bike on a quiet rural road through golden grasslands, in a vertical 9:16 composition. KEEP — Preserve the person's exact facial identity and natural appearance from the uploaded photo. Keep the original forehead, eyebrow shape, eye shape and natural eye colour, nose bridge and tip, lips, cheeks, cheekbones, jawline, chin, ears, facial width and natural asymmetry. Retain the original skin tone, visible pores, fine lines, natural marks and realistic skin texture. Preserve the existing hairline, hair density, hairstyle, hair texture and facial hair where present. Maintain the original neck, shoulder width, body proportions and recognizable physical appearance. Do not blend the face with another identity. CHANGE — Dress the person in a dark olive-green cotton overshirt with visible stitching, a fitted white crew-neck cotton T-shirt, sand-coloured cargo trousers with practical side pockets, clean white low-top sneakers and a muted brown baseball cap. Pose him with one foot slightly forward, one hand naturally holding the bicycle handlebar and the other resting beside his body. Keep the shoulders relaxed and the expression calm and confident. Use a narrow asphalt road, tall golden grasses, scattered shrubs and distant low mountains as the new setting. SCENE — Place the subject slightly right of centre, with the complete bicycle visible beside him. The road should recede naturally into the landscape. Keep the foreground grass detailed and the distant mountains softly blurred. Set the scene in late afternoon, with a pale blue sky and subtle atmospheric haze. LIGHT — Use warm sunlight arriving from the upper left, creating a soft golden rim along the shoulders and clothing. Illuminate the face from the same general direction with gentle, natural fill light. Preserve realistic facial shadows without making the face darker than the surrounding scene. CAMERA — Use an 85mm lens at f/2.8, with the camera at chest height and a natural perspective. Keep the face, clothing and bicycle clearly defined, with moderate background separation and anatomically correct proportions. GRADE — Apply warm amber highlights, earthy olive greens, muted golden grass and balanced natural skin tones. Use restrained cinematic contrast without excessive yellow tint or artificial HDR. OUTPUT — Generate a high-resolution, photorealistic vertical 9:16 image with the complete person and bicycle inside the frame. Preserve realistic fabric weave, road texture, bicycle geometry and natural body proportions. DO NOT slim the face, whiten the skin, change the eye colour, smooth the skin into plastic, invent jewellery or tattoos, alter the person's age, replace the face, distort the hands, add fingers, warp the bicycle frame or create broken spokes and wheels.
