Photorealistic Indoor Pool Lifestyle Portrait

3:4 vertical, photo-realistic, calm and natural indoor pool lifestyle portrait. A clearly adult fictional East Asian woman, around 22 to 26 years old, standing in the shallow water of a modern indoor pool, water level below chest, frame from top of head to under-thigh area. Subject centered, body slightly turned to the left, arms naturally submerged in water, legs faintly visible under clear water. She is not looking at the camera, but gazing to the right side distance, lips naturally closed, expression calm, restrained, slightly thoughtful, like a brief pause after swimming. She has a delicate oval face, fair neutral skin tone, dark brown almond eyes, natural eyebrows, a refined nose bridge, and bare pink lips. Minimal makeup: light semi-matte base, light gray-brown eye shadow, thin eyeliner, natural lashes, and low-luster lip color. Dark near-black short hair cut to chin or neck, completely wet, strands clinging to forehead, ears, and nape, retaining realistic wet hair texture. Face, shoulders, collarbone, and arms covered with fine water droplets and natural wet highlights. She wears a low-saturation deep red triangle bikini, thin strap neck, simple no pattern, wet fabric naturally conforming to body with realistic reflections, maintaining normal coverage. Pool water is light blue-green, surface forming natural refraction, ripples, and reflections in front of chest, underwater body slightly distorted by light refraction but with realistic proportions. Background is a clean modern indoor pool, light gray-white walls, large high windows, stone pool edge, and softly blurred blue water surface. Overcast natural light enters from left high windows, evenly illuminating face, shoulders, and water surface, creating cool gray-blue ambient light and subtle soft shadows. Overall low saturation, low contrast, slightly darkened, quiet, cool, with Japanese realism, independent film still, and high-end swimwear editorial quality. 50mm or 85mm lens, f/2.8, eye-level camera position, shallow depth of field, precise focus on eyes. Preserve realistic pores, fine vellus hair, water droplets, wet hair, swimsuit fibers, pool water ripples, and tile texture, slight ISO 400 film grain; no plastic skin, no over-smoothing, no exaggerated proportions, no deformed limbs, no extra people, no text, logos, watermarks, borders, or composites.
