I really like this shot but I only gave it a 6 because it is so over sharpened, the halos around the boats and on the horizon take away from this beautiful scene for me.
I get the strong sense there was a great deal of contrast between the sky and the boats in the original picture and that is why there is haloing around the boats caused by post processing. I applogize if you did this by design, but if it was unintended and you'd like to get rid of it I can suggest a method.
Over sharpening is evident here, see the bright halos around the boats and the horizon. The foreground is underexposed as well, but it's always hard to make the sky look good if you want the foreground well done.
