Beautiful shot. Excellent clarity, color and composition. For a 10 from me, horizon and boat look like they're a tiny bit off and would benefit from shifting about one degree to the left...or maybe it's that all the weight is on the right side and there's nothing on the left. Perhaps someone else would like to comment on this perception. It is a BEAUTIFUL photo worthy of a 10 if this minor issue could be resolved.
I don't think this is one of your stonger water pictures. I would have prefered to chop out a lot of the sky and focus in on the boat and the two sheds (which are partly cropped and loose detail with the underexposure). Perhaps a mild curve adjustment to bring out the dark parts may help. As it stands the point of interest (boat) is lost in the noise of the rest of the picture. Just my 2 cents.
Nice shot, but horizon does seem slightly off, and the boat is too central for me. Also, the most interesting part of the sky is the part at the bottom - the top doesn't really add too much to the photo.
