Ultra realistic cinematic full body portrait of a young couple

Create an ultra-realistic cinematic full-body photograph of a young South Asian couple walking together hand-in-hand on a quiet, elegant tree-lined street. The girl is wearing a stylish white sleeveless tailored vest with a black inner top, a thin black belt around her waist, matching wide-leg white trousers, and clean white sneakers. Her long, straight dark hair flows naturally over her shoulders, with white-framed sunglasses resting on top of her head. She is looking toward the boy with a soft, natural expression. The boy is wearing a red-and-white vertically striped oversized button-up shirt with the sleeves rolled up, loose black trousers, black shoes, and round dark sunglasses. He has thick, voluminous naturally styled dark hair. One hand is casually placed inside his trouser pocket while his other hand is holding the girl's hand. Pose: both are naturally walking side by side toward the camera, holding hands, with relaxed body language age. The boy is slightly turned toward the girl 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.
