I'm going with Bob Yankle more or less here with his analysis.

Further more, yes the rocks look interesting themselves, but if it were my shot, shot as it is, I'd crop the entire bottom half of the image out. Seascapes unlike flowers are typically sharp for focus throughout, but may certainly have motion blur. You might have tried a slow shutter speed (1/15 to 1/8 s; use a tripod if necessary) yet higher f-stop (8-11-16 depending lens and where you focus) to have de-emphasized the waves, leaving the rocks sharp. Out of focus and motion blur look very different (to most of us). You can try something like this again sometime. Other replyers gave you good ideas for salvaging this image.

I like your idea or intent. Your are thinking of various ways to make an image look. Just for most of us, the technique or execution needs a little work. You'll likely get it or get close to what you want next time.
