Realistic Japanese Track Athlete

Create a hyperrealistic vertical motion photograph with an adult as the subject.{argument name="athlete nationality" default="Japan"} The female track and field sprinter is depicted on an outdoor stadium track, framed from mid-thigh to above her head using a close-up portrait composition. She is in a pre-race crouching position, leaning forward with arms outstretched, her shoulders and upper body prominent. She wears a dark blue or black two-piece racing suit, consisting of a sleeveless cropped top and matching racing shorts, with thin red and white trim on the hips. A white race bib is pinned to her chest, displaying the sponsor's name in red Japanese and her race number clearly visible.{argument name="bib number" default="15-2"} The upper chest features a small white Mizuno-style logo. Her{argument name="hair color" default="Dark brown"} Long hair tied in a low ponytail, with a few strands shimmering in the sunlight. A simple rectangular privacy blur mask or solid skin tone block is added to the center of the face (from forehead to chin), while maintaining the realistic texture of the ears, hairline, neck, shoulders, and body. The background is a sunny athletic field with a red track and white lane lines, and the spectators and stands in the distance are rendered with a soft blue-gray blur effect. Natural light is used, with strong backlighting on the hair and shoulders, shallow depth of field, realistic skin texture, authentic sports photography compression, high detail, and a realistic professional photography style. It is not an illustration, not an anime, and there is no deliberate posing; there is no text except for the bib number.
