Photorealistic Poolside Portrait

Raw 8K photorealistic vertical portrait (9:16 aspect ratio) of a tall, athletic woman with a slender, toned frame, seated on weathered grey granite pavers on an outdoor poolside patio. She has a strong oval face with a sharply defined, elegant jawline, high sculpted cheekbones, and a straight refined nose bridge. Her deep warm dark-brown eyes have distinct limbal rings and realistic sclera vascularity. Her voluminous, layered dark brunette hair falls in flowing waves with soft face-framing strands, catching a natural sheen in the light. Her sun-kissed olive skin shows realistic subsurface scattering and visible tan lines. She wears a deep crimson halter-neck one-piece swimsuit with a central knot detail, and no jewelry of any kind. She is seated leaning back on her right hand, with her left hand raised to shield her forehead and eyes from the sun, fingers naturally relaxed. Her legs are extended forward toward the camera, with her bare feet fully visible resting on the stone pavers, toenails painted glossy white. Behind her is a reflective glass sliding door and a wicker armchair. Hard midday sunlight creates high contrast with sharp shadows and realistic micro-glints on her skin and the swimsuit fabric. The composition is a medium close-up portrait emphasizing her torso, face, and extended legs and feet, in razor-sharp focus with no artifacts and no skin-smoothing or beautification — preserve natural skin texture. Critically, any reflection in the glass sliding door must maintain perfect structural and color consistency with the real subject and background, with exact spatial alignment, no ghostly duplication, and no clipping. Avoid: jewelry, bracelets, necklaces, blonde or light hair, extra limbs, distorted features, logos, and text.
