Ritratto sportivo di velocista accovacciata

An ultra-realistic vertical sports photograph of an adult [Japanese] female track-and-field sprinter on an outdoor stadium running track, framed from mid-thigh to above the head in a close portrait crop. She leans forward in a pre-race crouch with both arms extended downward, shoulders and athletic upper body prominent. She wears a dark navy or black two-piece racing uniform consisting of a sleeveless crop top and matching briefs with thin red-and-white trim at the hips. A white competition bib is pinned across her chest featuring red Japanese sponsor lettering and race number [15-2], alongside a small white athletic brand logo on the upper chest. Her [dark brown] hair is tied back in a low ponytail with loose wisps catching the light. A plain rectangular solid skin-toned privacy block covers the face from forehead to chin, leaving the ears, hairline, neck, shoulders, and muscular form naturally visible. Outdoor sunny stadium setting with a red synthetic track, crisp white lane markings, and distant bleachers blurred into soft blue-gray bokeh. Authentic sports telephoto lens compression, shallow depth of field, natural daylight with rim lighting on hair and shoulders, genuine skin texture, candid documentary sports photography.
