Full-body photorealistic portrait of a young man

Full-body photorealistic portrait of a young man standing in a sunlit park with lush green bokeh background, soft diffused daylight, shallow depth of field. He wears a white, subtly patterned button-down shirt with sleeves rolled to the elbows and slim-fit white pants; right hand casually in pocket, left arm relaxed by his side. Well-groomed dark hair and short beard, wearing round black sunglasses and a black wristwatch on the left wrist. Natural, confident pose, slight three-quarter turn to camera, relaxed expression. Crisp texture on fabric and skin, accurate skin tones, gentle rim lighting, warm natural color grading, high resolution, 85mm portrait feel, f/1.8 shallow focus, soft cinematic vignette, pleasing composition with subject centered and blurred foliage depth. 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.
