Vertical 9:16 ultra-realistic beach motion portrait. A young adult woman with fair natural skin tone, real skin texture, lively smile and natural human presence runs happily toward the camera on a beach. She wears [swimwear color] swimwear with [outer layer]. No oily shine, no waxy skin, no plastic skin, no CGI look. Extreme low-angle shot from near the sand or shallow water. One foot steps forward into the foreground toward the camera, partially visible sole, strong but natural front-foot perspective. Body leans forward, back leg pushes off, hair and fabric move in the sea breeze. Hair must be clear, continuous and realistic: connected strands, clean edges, no blurry hair, no broken hair, no fake wig, no AI collage look. Real beach background, ocean waves, sand, sky, natural coastline, small flying sand or water splash. Candid photography, joyful summer mood, strong perspective, realistic motion. No text, no poster layout, no eye-level shot, no standing pose, no oily skin, no distorted feet, no bad toes, no fake background.
