Studio commercial portrait, vertical poster 2:3, clean minimalism: one young man, fair skin, natural hair with a neat haircut, no beard or very well groomed, soft confident expression; he is sitting in a modern rounded designer armchair/soft lounge chair (bulky, sculptural shape), legs casually crossed, relaxed open pose; outfit in contemporary casual style: bright blue monochrome set (jacket and pants) or with subtle geometric accents, white socks and chunky light sneakers; background is a smooth seamless blue gradient (slightly darker at the top, lighter at the bottom), no text, no logos, no letters, no poster typography. Lighting: three-point studio setup, large soft key light (octabox/softbox) placed front-side and slightly above to model natural volume on face and clothing; gentle fill light or reflector on the opposite side with lower power to lift the shadows while keeping depth; subtle rim/back light from behind to create a clean outline along shoulders and hair and to separate the subject from the background; overall soft, controlled shadows, no harsh edges. Shadows and rendering: contact shadow under the chair and feet, very soft background shadow or gradient behind the subject, no dirty vignette; clean commercial retouch, realistic skin texture, moderate micro-contrast, high detail in fabric and sneakers, 4k, ultra sharp, photorealistic studio quality.
