Edit the uploaded image to modify the boy's appearance and background. The boy should now have a happy, cheerful smile on his face, showing his teeth. On his head, replace his denim cap with a colorful, festive birthday party cone hat. Completely remove the original background (park, flowers, trees, bench, and other people) and replace it with a clean, solid, pure white background, effectively cutting the boy out. Keep his original pose with hands on his hips and his white t-shirt. High-quality edit, clean edges.
