Selfie Spontaneo Post-Pilates con Smartphone

[Tatum] attempting a candid, high-angle post-workout selfie ten minutes after a reformer Pilates class. She is sweaty, slightly annoyed, and intensely focused on her phone's screen rather than the camera lens. She balances her smartphone precariously on a water bottle refill station in a dim studio corner. Direct, harsh smartphone flash lighting illuminates her, highlighting subtle muscle definition in her abs and back while casting sharp shadows, contrasting with faint ambient studio light in the background. Candid aesthetic, raw smartphone camera snapshot.
