Ultra-realistic vertical photo (9:16). A young man (use uploaded face, 100% identity lock, no alteration) sits on indoor stairs beside a matte concrete wall. A rectangular beam of golden sunlight from a window hits the wall, creating a crisp shadow silhouette inside the bright frame. 
He wears a black ribbed knit sweater, tapered grey chinos, and chunky white sneakers. 
Pose: seated, elbows on thighs, hands loosely clasped, chin slightly lifted, eyes looking toward the light, calm and confident expression. 
Lighting: hard warm sunlight from camera-right as key, soft ambient bounce fill, high contrast with long shadows, cinematic golden-hour mood. 
Camera & look: low-mid angle from a few steps below, 50–85mm f/2.2 lens, shallow depth of field, clean optics, realistic skin texture, fine film grain, subtle vignette. 
Style: minimalist background, no clutter, fashion editorial realism. 
Exclude: cartoon, CGI, AI-artifacts, over-smoothing, plastic skin, excessive sharpening, motion blur, warped anatomy, extra fingers, disfigured hands, double shadow, blown highlights, banding, watermark, logo, text, bad perspective, dirty wall, clutter.
