I'll offer a comment, if you don't mind nits meant to be constructive. The colors of sand and water are sublime. For me, the black rocks on the left are very distracting and disturb the balance/weight factor. In looking for your center of interest, my eye tends to fall on the middle part, but I don't think that's what you intended. You may have seen it more as a color field, which it is, but the black seems inconsistent. I tried covering up the rocks, but what's left then all slants off to the left. Honestly, I don't know what the solution would be here.
