Prompt realista de selfie no espelho de estúdio de fitness

A highly detailed realistic photograph of a young woman with vibrant reddish-orange hair styled in a neat high bun, kneeling gracefully on a light blue yoga mat in a modern fitness studio. She is wearing a casual red short-sleeved crop top tied at the front waist and matching red athletic shorts featuring bright yellow side stripes. She holds a red smartphone in her right hand, capturing a mirror selfie while looking back over her shoulder with a gentle smile. The background shows a spacious gym interior with large floor-to-ceiling mirrors reflecting the room, exercise equipment including treadmills and weight machines, polished flooring, and soft ambient lighting from overhead fixtures and large windows. The overall scene is clean, well-lit, and conveys an active lifestyle atmosphere with precise details on clothing textures, hair strands, and gym environment elements.
