Cinematic Stadium Sports Portrait

A photorealistic cinematic outdoor sports portrait of a {argument name="subject" default="young woman"} preparing for a run on an empty athletic track inside a large stadium. She has {argument name="hair style" default="dark-brown hair tied into a high ponytail"} with a few loose strands framing her face. She wears a simple black athletic tank top, black running leggings, and white athletic shoes.
She is captured in a natural running pose, one knee raised slightly as if warming up, with a focused yet calm expression while looking toward the side. The stadium behind her features rows of empty blue seats and a large covered grandstand.
Warm golden-hour sunlight streams across the stadium, creating beautiful rim lighting around her hair and soft long shadows on the track. Realistic skin and hair texture, detailed athletic clothing, natural proportions, shallow depth of field, subtle lens flare, cinematic sports photography, warm sunset color grading, authentic candid atmosphere, highly photorealistic, vertical 4:5 composition.
