Subject: A youthful Japanese student beauty looking back from a side profile, with a sweet and confident smile, wet and slightly messy hair, realistic skin texture with visible fine pores, showcasing the rosy transparency of subsurface scattering. Clothing: A navy blue competitive one-piece swimsuit combined with white shoulder straps, made of high-elastic nylon presenting high reflectivity when wet, tailored to fit the body curves with crisp edge folds. Decorations: Crystal-clear water droplets clinging to the back and arms, with light refracting on the surface of the droplets to create tiny highlights, and well-proportioned muscle lines with firm tension. Background: Beside a tranquil indoor swimming pool, the clear water surface showing dynamic shimmering beauty, with the background architectural structures creating a silky bokeh effect under a shallow depth of field. Style: 85mm portrait perspective, F/2.0 large aperture, High Dynamic Range (HDR), fresh and bright colors, natural diffused light and shadow, top-tier photorealistic quality.
