A photorealistic close-up portrait of a young man standing in an infinite white void with no visible walls or ceiling, like a seamless white cyclorama. The camera is very close to his face, shot on an ultra-wide 14mm lens with subtle perspective distortion, his face centered in frame. He is drinking juice from a small cardboard carton with a straw; the carton has early-2000s retro tech packaging vibes inspired by Windows XP color blocks (no readable branding). He wears an oversized crisp white button-up shirt, loose black trousers, chunky black shoes, thin round glasses, slightly messy dark hair; calm, detached expression. Soft studio lighting from above and slightly front, gentle shadows, high skin and fabric detail, slight glossy highlights on the carton, shallow depth of field focused on the eyes and the straw.
