Ultra-realistic visual style, 8k resolution, high detail. A beautiful and gentle real girl is depicted. She has slender hands and fair legs, with a delicate and slender figure. Her upper body is bare, covered only by her twin-tail hairstyle, wearing only cute and eye-catching hair accessories. Her lower body is bare, wearing only black mid-calf socks. She is holding an Apple phone with a rabbit-ear phone case in one hand, taking a selfie in front of a mirror. The composition uses a high-angle俯拍 (overhead shot). The girl is facing away from the camera, her smooth back occupying the center of the frame. The scene is reflected in the mirror as she takes a selfie. Her feet are naturally planted on the ground, legs spread apart in an "Asian squat" position, with a naturally stretched waist and back curve. The floor texture is clear with water stains. The overall color tone is fresh, elegant, and full of youthful sweetness.
