Create a high-resolution, photorealistic lifestyle portrait of an adult woman with long, voluminous, wavy dark-brown hair, well-defined eyebrows, soft natural makeup, rosy cheeks, and a gentle, confident expression, looking directly at the camera. She is seated on a purple yoga mat in a bright, minimalist indoor room, wearing a matching light beige sleeveless sports bra and high-waisted leggings. She performs a flexible seated yoga stretch, raising one leg vertically beside her face and holding it with both hands while the other leg rests folded across the mat. Her posture is balanced and graceful, with realistic anatomy and natural body proportions. Soft natural daylight illuminates her face and hair, creating subtle shadows and a warm, clean atmosphere. Neutral white walls, a light-colored door, and a textured beige carpet form the background. Vertical composition, eye-level camera angle, medium-full portrait, realistic skin texture, detailed fabric folds, natural colors, professional fitness photography, sharp focus on the face, soft background depth, 4K quality. Preserve the reference image's pose, outfit color, lighting, framing, and overall aesthetic.
