Moody Studio Full-Length Portrait of Stylish Man Seated on Black Chair in Red Lighting

A photorealistic vertical full-length studio portrait in exact 7:10 aspect ratio (matching 736x1051 proportions), faithfully recreating the dynamic low-angle composition, scale, framing, and dramatic mood lighting of the reference image. A stylish young man sits casually on a black metal bistro chair, strictly preserving the original 7:10 vertical proportions, upper headroom, floor foreground, and subject-to-frame scale. Faithfully preserve his recognizable facial identity: fair-to-medium skin tone, defined jawline, full groomed dark beard and mustache, rectangular dark-tinted sunglasses, and textured, wavy dark brown hair styled with damp-look strands falling over his forehead. He leans forward with forearms resting on his knees, hands dangling naturally, wearing rings, a black wristband, and a metal bracelet on his wrists. He is dressed in a monochrome olive-drab or army green utilitarian streetwear set featuring a relaxed-fit long-sleeve button-up overshirt with rolled cuffs, paired with loose-fit, baggy matching green cargo pants draped naturally over chunky off-white platform sneakers; match the loose, relaxed, and roomy silhouette of the pants with natural fabric stacking without making them tight or slim. The background is a seamless studio cyclorama backdrop illuminated by a soft, dramatic crimson-red gradient spotlight with deep shadowy vignettes, casting moody highlights and soft ground shadows on the studio floor. Authentic skin texture with visible natural pores, sharp subject focus, cinematic color grading, 8K Ultra HD quality. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
