This is a very nice scene, but the photo lacks impact for me. With the waves hitting different directions and a broken up sky that doesn't seem to have flow to it, this photo seems very disjointed.
when I see an image that is less than 800px ( on the long end) my first thought is " hmm, what is he/she trying to hide?"
overall this looks very nice, and you should show it off as large as you can. good luck
