Casual Studio Portrait in Yellow Sweatshirt

A photorealistic medium close-up studio portrait of an attractive South Asian man with warm skin tone, a full dense dark beard, and a mustache, strictly preserving the exact square 1:1 aspect ratio, centered framing, and headroom of the reference. He wears a vibrant yellow backward baseball cap with black embroidered lettering across the back strap, and a matching mustard-yellow oversized crewneck sweatshirt featuring a relaxed, dropped-shoulder silhouette, roomy torso, and a small blue bird silhouette emblem embroidered on the center chest. Leaning slightly forward toward the camera with a relaxed, friendly half-smile, looking directly into the lens. The background is a seamless, solid warm mustard-yellow studio backdrop matching the tone of his outfit. Soft, diffused warm studio lighting creates gentle natural shadows and realistic skin textures, 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.
