Of the three images on this page, I like the first, top one the best. I like the blue water. You can instantly tell where the land and water are. The second one I have to look at for a second or two before I can make out what is what. So I'd start with the top one. You could desaturate it a bit, but I'd definitely keep it two-toned with the blue. I think the weathering looks fine and natural. It doesn't distract me at all.

And the red one just looks weird.
