产品视觉 GPT Image 2 提示词：Realistic Female Track Athlete Portrait

Create a realistic full-body vertical portrait of an adult female track-and-field athlete standing upright and facing the camera against a plain gray concrete wall with circular form-tie holes. She has a fit, athletic build with toned shoulders, arms, waist, and legs, and wears a {argument name="uniform color" default="deep red"} two-piece competition uniform: a racerback sports crop top with white curved side stripes and small white athletic logos on the chest, plus matching low-rise running briefs with white side stripes and a small white logo near the hip. Her {argument name="hair color" default="reddish brown"} medium-length bob hair is softly styled with outward-flipped ends, and her face is covered by a centered rectangular pixelated privacy block in a skin-tone color. Use bright natural sunlight from the upper left, realistic skin shading, subtle shadows on the wall, sharp high-resolution detail, straight-on camera angle, cropped from head to mid-thigh, documentary sports portrait style, no text, no extra people, no props.
