Create an action-packed sports image featuring a basketball player mid-air, about to dunk a basketball. The player should wear a bright blue jersey with a large, stylized number on the front. The shorts should match the jersey, with a dynamic design. The background shows a vibrant basketball court filled with cheering fans, blurred to focus on the athlete. Remove any brand logos or trademarks, and ensure the player’s facial expression conveys intense concentration and determination. Add motion lines around the player to emphasize the energetic movement.
