Ultra realistic full body street wear fashion portrait

Ultra-realistic full-body streetwear fashion portrait of a stylish young man leaning casually against a modern minimalist grey paneled wall. He is looking downward with a soft natural smile, messy voluminous black hair, relaxed and confident pose, both hands inside his pockets, and one leg slightly bent.

Clean modern urban background with grey stone pavement, soft natural daylight, realistic skin texture, detailed fabric texture, professional DSLR photography, cinematic depth of field, sharp focus on the subject, natural colors, high detail, realistic proportions, fashion editorial style. Vertical full-body composition, 3:4 aspect ratio, ultra-realistic, 8K 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.
