Hmm,
Well the exposure seems pretty good and the horizon is level so thats good. The only thing is there is nothing to look at, maybe the sea spray would look more effective if you included whatever was causing it to fly into the air in the pic. As it stands there is nothing to really focus the eye on so it is kinda ... pointless? (Sorry that sounds really harsh and i dont mean it to be but I cant think of another way to put it).
Hope that helps,
Chris
