Photorealistic photograph of a beautiful adult woman in the exact same pose, body position and camera angle as the reference image. She is on all fours on a polished wooden floor, knees and hands supporting her weight, torso slightly arched, looking back over her left shoulder directly at the camera with a soft, playful smile and slightly narrowed eyes. The camera is positioned at a slightly elevated rear three-quarter angle, focusing on her lower back, hips and the turned face. Preserve the exact hairstyle from the original, long wavy brown hair tied in a low ponytail with a soft pink hair tie, a few loose strands framing the face and neck. Preserve the exact clothing from the original, tight light-pink sports bra with thin white trim along the edges and matching high-waisted light-pink leggings with a subtle white side stripe, fabric clinging naturally to the body and showing realistic folds and tension. Highly detailed realistic skin texture with visible pores, subtle sweat sheen, natural muscle definition and soft shadows. Natural daylight streaming through the large wooden-framed window behind her, revealing a sunlit European-style cityscape. Wooden floorboards with realistic grain and reflections. Partial view of gym equipment on the right. Cinematic natural lighting, sharp focus, 85mm lens, shallow depth of field, 8k resolution, photorealistic, ultra-detailed.
