Create a realistic natural-motion video from this image. Keep the girl’s face, hairstyle, clothes, body proportions, background, and iPhone 13 Pro Max exactly consistent with the original image. Animate her as if she is casually taking a selfie with the phone in her hand. Add subtle natural hand movement, slight wrist movement, gentle head movement, natural blinking, soft facial expressions, and realistic breathing. The phone should move naturally with her hand while remaining clearly visible. Add a very slight handheld selfie-camera feel, smooth realistic motion, natural lighting, and cinematic quality. No face distortion, no extra fingers, no warped hands, no changes to clothing or background, and no sudden movements
