Fit young woman relaxing on bright pink rooftop

Photorealistic image of a fit young woman with tanned skin and long brown hair in a high ponytail, wearing a light gray sports bra and matching high-waisted shorts. She sits on a bright pink outdoor surface with one knee bent and one hand resting on the ground, the other hand on her knee, looking slightly to the side. Setting is a sunny day with a clear blue sky, a glass railing in the background, and distant low hills. Lighting is natural daylight with soft, defined shadows and subtle hair rim light. Textures: crisp fabric details, slight sheen on the athletic material, visible skin texture, and reflections on the glass railing and pink surface. Color palette contrasts cool gray outfit with warm pink platform and vivid blue sky. Composition uses a shallow depth of field (50mm lens, f/2.8) to keep the subject sharp while gently blur the distant hills. Mood: relaxed, athletic, summery.
