Candid Portrait in Open Plaid Shirt.

"A realistic portrait of a young man with a confident, slightly brooding look, shot from a low angle with his head tilted to one side and his gaze directed at the camera. He has dark, wavy, slightly messy hair peeking out from under a black washed-cotton baseball cap, and a full, well-groomed beard and mustache. He wears a green, black, and maroon plaid flannel button-up shirt, worn open to show his chest and abs, with the sleeves loosely rolled up. His hands rest in his pockets. The background is a clean, minimal white wall in a softly lit indoor space. Soft, diffused natural window light, gentle shadows, shallow depth of field, natural skin texture, fashion-editorial style, shot on a smartphone, 3:4 portrait aspect ratio, cool neutral tones with deep green and warm skin tones." 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.
