Lots of ways you can take an image ...
The sky is blown out on what you've posted, so I couldn't do anything really with it, but you get the gist of what I'm doing here with it. I'm diggin' the white (high key) to black (low key) thing that (I think) you're going for, but I'd like to have a bit more of the sea / sky to work with so it isn't totally blown and void of detail ... with at least a little transition from sea to sky before fading to blown white.
Of course, that's my vision ... not necessarily yours.
As always, S&P to taste ... but I can see you've got an eye and a vision ... just gotta learn how to cook 'em how you like 'em.
