Generate a high-definition, realistic image of a girl in her 20s running, wearing jeans and a white shirt. The girl should be facing away from the camera, with her right side turned towards the lens. Make sure she is dressed professionally in jeans and a shirt. The image should look like it was captured with a high-quality, professional camera, focusing on natural motion and a lively expression. The background should be plain or minimal to emphasize the subject and the dynamic movement of her run.
