Cool walking image prompt

Ultra-realistic full-body photo of a young Indian man in his early 20s with curly dark hair, light beard and mustache, wearing black rectangular sunglasses. He is walking forward between two tall dark speckled granite walls toward the camera, one hand slightly swinging, other near his pocket. Black crossbody bag across his chest. He is wearing a crisp white short-sleeve button-up shirt (slightly wrinkled), black wide-leg jeans with yellow drawstring, white chunky sneakers. Bright vertical light slit in the background creating strong geometric shadows on the walls and floor. Low-angle shot, natural skin texture, sharp focus, photorealistic, Instagram fashion style. 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.
