Subject:\nSummer hair tied at the white sand beach\n\nMain Character:\nA young adult woman sitting sideways on a tropical beach with crystal-clear turquoise water and white sand, with her back to the camera. The figure is placed large in the center of the frame, highlighting her from head to toe, her white ruffled swimsuit, raised arms, and ponytail.\n\nPerson and Expression:\nBright, smooth skin, a small oval face, a neat nose, and pale pink lips. She is shown in a refined profile facing left, with eyes closed and a calm expression as if feeling the summer breeze. Her hair is light brown with thin bangs and delicate stray hairs, tied in a high, long ponytail. The hair bundle sways to the bottom right in the wind, with sunlight shining through the fine strands.\n\nClothing and Pose:\nA pale ivory-white halter-neck swimsuit with delicate sheer chiffon ruffles under the bust and around the waist, and thin strings tied at the neck, back, and both sides of the hips. She sits sideways on the sand with her knees bent to the sides, back straightened and waist slightly twisted. Both arms are bent over her head, with the right hand holding the base of the ponytail and the left hand layered over the top of her head. Fine sand clings to the soles and toes of her feet.\n\nBackground and Light:\nShallow turquoise sea and a thin shoreline from the left to the center, bright blue sky above, and white sand with dense green coastal forest in the background on the right. Bleached thick driftwood and branches are in the foreground and background. Strong midday direct sunlight from slightly top-left illuminates the shoulders, back, waist, and thighs, casting short, sharp shadows on the sand. Reflective light from the sea surface softly fills the shadow side.\n\nComposition and Camera:\n3:4 vertical aspect ratio. A full-body portrait captured from a natural eye-level camera slightly above the sand surface, from a back-diagonal-right angle. The raised arms occupy the upper half, the back and waist in the center, and the bent legs and feet in the lower half, with a little blue sky margin left above the head. Precisely focused on the person, with the coast and driftwood softly blurred in a shallow to medium depth of field.\n\nTexture and Style:\nA high-definition photorealistic live-action photograph taken in strong summer sunlight. Realistically depicts natural skin texture, fine hair strands including backlighting, chiffon transparency and ruffles, thin strings, sand grains, the wet shoreline, and the dry texture of driftwood. Bright tropical colors of white, turquoise, and blue sky, avoiding excessive skin retouching or illustration styles.\n\nNegative:\nAlteration of sideways sitting, position of arms and hair, white swimsuit, or profile face.
