{ "prompt": "Ultra-realistic full-body portrait of a stylish young man standing beside a riverside promenade during sunset, pose identical to the reference image: body slightly angled away from camera, one hand casually touching shirt near chest, other arm relaxed by side, head turned sideways looking off-frame with a calm confident expression. Wearing dark sunglasses, brown casual button-down shirt with sleeves rolled up, beige chinos, white sneakers, wristwatch visible, neat modern haircut and trimmed beard. Background shows a large steel truss bridge spanning across a river with the glowing setting sun behind it, warm orange sky reflecting on the water. Soft cinematic golden-hour lighting, shallow depth of field, realistic skin texture, sharp focus on subject, blurred background bokeh, professional DSLR photography, natural color grading, ultra-detailed, high dynamic range, 8k quality.", "size": "4:5" }
