That's a beautiful shot. I really like those birds, I sometimes see them at a certain spot on a river in my home town. They are quite quick though, it is relatively hard to take pictures of them.
I don't know where that is, but it looks like it would be all kinds of awesome with some repair and cleaning.
I realize that is a blue hole, but darned if that doesn't look like a gigantic eyeball... Obviously, Mother Earth is watching for... well, something...
