Portrait studio minimaliste d'un homme sur une chaise

A full-length studio portrait of [a young man with dark, messy hair], sitting in a casual, relaxed pose on a modern minimalist chair against a seamless solid neutral gray backdrop. The man has light skin, a defined jawline, dark messy hair, and a well-groomed beard. He wears glossy black-rimmed round eyeglasses with smoky semi-translucent lenses, looking directly forward with a confident expression. His torso is angled slightly to the left, his right arm resting casually on the chair's backrest, left hand resting in his lap, right foot planted, and left leg fully extended forward. Outfit: an [oversized, heavy-knit long-sleeve crewneck sweater in solid black] with detailed ribbed textures, loose-fitting light-wash denim jeans creasing and bunching around the ankles, and black and white low-top leather sneakers. The chair features a molded matte black shell seat on thin white tubular metal legs, angled toward the right. Eye-level full-body framing with ample negative gray space. Soft, diffused studio lighting from the front-left, casting subtle highlights and soft shadows on the floor. Monochromatic color palette of neutral gray, solid black, denim blue, and crisp white.
