9:16 vertical photorealistic beach running portrait. An adult East Asian young woman, 20–25 years old, sweet youthful look, natural joyful smile, direct eye contact with the camera, running toward the lens through shallow waves. Casual lightly wet but opaque short-sleeve shirt, dark pleated skirt, barefoot. Wind-blown hair, light splashes around the feet, face clear and natural. Real candid handheld photo feeling, slight motion blur only on the image edges, waves, splashes and hair strands. Natural matte skin, real skin texture, no oily highlights, no glossy face, no plastic skin, no heavy retouching, no AI influencer face. Create separate variations: overcast wind, soft pink dusk, golden sunset, blue-purple twilight. Avoid face looking away, side-running pose, wet hair covering the face, water splashes covering the face, over-polished lighting, strong glow, dreamlike filter, CGI look, distorted hands or legs.
