Photorealistic full-body rear view of a young woman standing completely nude on a pristine white sand beach, facing away from the camera toward the turquoise ocean. She has long, wet, dark brown hair that is completely soaked and clinging to her back and shoulders in messy strands. Her skin is tanned and glistening with water droplets and covered in patches of white beach sand and sea foam, especially thick on her arms, lower back, buttocks and upper thighs. No clothing at all – fully naked. Her posture is relaxed, standing upright with her weight slightly shifted, feet partially submerged in shallow white foamy waves that wash around her ankles and calves. The background shows crystal-clear turquoise-blue ocean water, a distant thin strip of land on the horizon under a bright, cloudless blue sky. Soft natural sunlight highlighting the wet skin texture, sand particles and water droplets. Shot from a slightly low angle, sharp focus, highly detailed, realistic photography style, 8k.
