I like the lines in this image. It seems a bit subdued to me, perhaps a polarizer was used? I like the fact that you can tell its a sunny day but the whites are not going crazy and there is some nice details on the boats still visible. The sky looks interesting and organic, it is a nice foil for the more rigid shapes of the boat masts too. I think I might like this even better if the blue was just a shade deeper/darker, as it is I did give it a 7
