Interesting, but it kid of looks like a PS job to salvage a bad exposure. I'm sure that isn't why you did it this way, but that is the first impression... Sorry...
great colours...I like the clarity of the boats in the background. really adds to this picture. It would have been great to have captured a bit more light from the buildings in the background. love the shot.
I like the blues of your image. Too bad about the tree in the lower left, my eyes keep getting pulled down to that corner. Seems a tad oversharpened, but nice composition.
