This image makes me laugh. I know it was spur of the moment so some of the things would have been harder to control.
- Distracting elements. They don't really need to be there so crop or clone them out.
- The faces of the bears are blurry. It they were in focus this would be a much more powerful shot. This must have been taken suddenly at a lower aperture. Knowing that the shot is there, set the aperture to f22 and wait until it comes along again.
- The back of the bears is awful bright. Adjust the EV or tone it down in post.
- The child's face is not lit. He and the bears are the subject, so they should be equally lit.
I almost said something about the foreground post. However, it leads your eye right to the kids. It's a great leading line that draws you into the shot.
