Retrato en la Pista de Tenis Mirando Atrás

Photorealistic vertical portrait of an adult woman standing in the center of a sunny outdoor tennis court with her back to the camera, looking back over her right shoulder toward the lens. - Person & Expression: Calm expression with closed pale pink lips, slim oval face, wide brown eyes, natural thin eyebrows, and long wavy light brown hair flowing down her back. - Clothing & Pose: Wearing a [mustard-colored] sleeveless top with a deep open back and a [short white pleated tennis skirt]. Weight shifted onto one leg with slightly twisted hips, right hand holding a white tennis racket pointing down toward the lower right, left arm relaxed at her side. - Setting & Lighting: Outdoor [orange] tennis court with a black net crossing the foreground at waist height, enclosed by green fencing, distant trees, and a clear blue sky. Harsh direct midday sunlight from the upper left, casting short shadows and highlighting the hair and shoulders. - Composition & Camera: 4:5 vertical knee-up shot from a low, waist-height diagonal rear perspective. Sharp focus on her face and bare back, with a slightly blurred background. - Constraints: The subject must be looking back over her shoulder rather than facing forward; include the waist-level net in the foreground and the racket in the bottom right corner.
