Awww, so cute!
To be clearer, are you asking what you could have done better, or what you can do now (with software)? The focus is off somewhat, but I don't think there's much you can do to fix that.
As for cropping, I would definitely try to take out the shoe in the upper right corner. You might try cropping the left and bottom to remove the girl in the picture - it's hard to tell if that will remove the perspective of the pig jumping over the hurdle.
