Young Woman Gym Selfie on Yoga Mat - Fitness & Wellness

We're looking for an authentic gym mirror selfie of a young woman, sitting cross-legged on a blue yoga mat. She's holding a smartphone in her right hand, taking the selfie, with a small workout towel in her left. Her expression is a relaxed, slightly tired but satisfied post-workout smile, looking into the mirror. Her dark brown hair is in a high messy, damp ponytail, and she's wearing a dark gray top, black high-waisted leggings, and a fitness watch.

The setting is a minimal modern gym, with a power rack, dumbbells, and a cable machine visible in the large mirror wall. A stainless steel water bottle is in the foreground. We need bright natural indoor lighting, creating soft, even illumination. The mood is healthy, real, and candid. Focus on ultra-photorealistic detail, showing natural flushed skin, visible texture, pores, and a slight sweat sheen, all rendered in high resolution with neutral fitness photography tones.
