very nice :-)
The water should be more blueish, I think. also the shore needs some foam. Lastly, the part of the beach that get's wet from the waves should be darker than the sand that stays dry.
A little bit of flotsam and jetsam could also add to the realism. As well as footsteps would. In the end, the captain of the little boat must have gone or come from somewhere, no
?
Cheers,
