I'm the end I left it as it is. One of the things I like about this shot is the way the guy was doing pretty incredible somersaults on the sand - but most people in the image are not even looking at him... In the end I thought that was part of the story of the shot.
I quite like number One , I'd crop the water out to the left of the tree (or at least that bit of arm once you notice it you can't unsee it!) and clone whatever that is bottom right A rock?
