Photorealistic Fitness Studio Portrait with Smartphone Mount

A young woman with fair skin, delicate natural facial features, bright light-colored eyes, and long copper-red hair styled in a loose low ponytail. A few soft strands fall naturally around her forehead and cheeks, giving her hairstyle a relaxed, effortless appearance. She is smiling warmly toward the camera with a cheerful, friendly expression. She stands facing the camera in a casual, confident posture, with one hand lightly holding the phone mount while the other arm rests naturally by her side. She is wearing a deep burgundy-red fitted sleeveless athletic-style one-piece outfit with thin shoulder straps and a clean minimalist design. The fabric has a smooth stretch texture with subtle natural folds and realistic highlights. Her accessories are kept minimal so the outfit and natural appearance remain the visual focus. The scene takes place inside a modern studio or fitness space with a polished light wooden floor and a dark, almost black interior wall behind the subject. Several long horizontal ceiling lights are visible in the background, creating a contemporary studio atmosphere. A smartphone mounted on a tall adjustable stand is positioned in front of her, clearly establishing the image as a casual recorded fitness or lifestyle session. Use bright controlled indoor lighting from overhead studio fixtures, combined with subtle frontal illumination on the subject. Create realistic highlights in the hair and gentle shadows around the face and clothing while maintaining balanced exposure. The dark background should provide strong visual separation from the subject without appearing overly dramatic.
