Monochrome Studio Portrait of Smiling Young Man in Baggy Denim

A photorealistic vertical black-and-white studio portrait in 3:4 aspect ratio of the young South Asian man from the reference image, faithfully preserving his recognizable facial identity, facial structure, genuine warm smile showing teeth, full trimmed beard, mustache, and thick dark curly textured hair styled casually over the forehead. Seated on the floor against a smooth, solid neutral studio backdrop with his knees drawn up and spread wide, he leans forward slightly while resting his forearms across his knees with relaxed, loosely clasped hands, smiling directly into the camera lens. He is dressed in a relaxed-fit, loose short-sleeved black button-up collared shirt, paired with distinctly loose-fit, baggy, relaxed, and roomy wide-leg denim jeans that pool naturally over two-tone chunky skate sneakers; match the loose, relaxed, and roomy silhouette of the reference, avoiding a tight or slim fit. Studio softbox lighting creates soft ground shadows, natural grayscale contrast, and authentic skin texture with visible natural pores. Sharp subject focus, clean composition, strictly preserving the original vertical 3:4 aspect ratio, framing, headroom, and subject-to-frame scale of the reference photo. 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.
