Lovely feeling, great sand texture and reflections.
Seems to me you selectively lightened up the foreground rocks, which raises the question what is the main point of interest, the rocks or the surfer? If it were my image, I would leave the rocks as they were, ie, presumably darker. I would also flip the image. That way you would have two strong leading lines, the rocks pointing diagonally left-to-righ to the surfer, and a gentle curve doing the same from the right side.
