Ultra-realistic cinematic live-action film still, vertical 9:16. A beautiful 6-year-old little girl with delicate childlike facial features, large expressive hazel-brown eyes, soft fair skin, long slightly wavy light-brown hair, wearing a simple pale-yellow raincoat over a white dress and small white rain boots, standing completely alone on a wet city sidewalk during a heavy rainstorm. She holds a tiny transparent umbrella above her head, but rain is blowing underneath it. Her hair is slightly wet, her cheeks have tiny rain droplets, and she looks anxiously down the empty street as if waiting for her mother. Wet pavement reflects streetlights, blurred pedestrians and cars in the distant background, cold overcast atmosphere, cinematic depth of field, realistic skin texture, realistic rain physics, subtle film grain, emotionally heartbreaking expression, high-end Hollywood cinematography, photorealistic, no text, no watermark, vertical 9:16.
