Use the attached photo as the reference for the person, keeping her face, facial features, skin tone, hair, body type and identity exactly as they are, with no retouching that changes who she is. If no photo is attached, use the Subject Description below.
Show her taking a candid selfie during the Stretch Pose on the yoga mat in the Setting. Use the Selfie Framing, with a naturally imperfect arm's-length composition and a relaxed expression that feels captured between movements rather than posed. Let the Window Light fall gently across her face and body, with soft shadows and subtle highlights. Include enough of the surrounding room to establish the everyday fitness setting without distracting from her. Keep the yoga mat, phone perspective and body proportions realistic. Use natural skin texture, an authentic lifestyle photography look and a calm, active mood. Avoid exaggerated flexibility, distorted hands, warped facial features and overly polished retouching.
