With all of the browns in the water, dock & rust that bright blue rope is out of place. This is advanced editing, I'm sure you could have done something to "fix" that. :)
Not really a good color for a river, is it? And from the looks of the water line on the boat it appears to be rather caustic.
I think I would have changed the color of the blue rope to something less vivid (maybe brown to blend in) and probably straightened the boat or tilted it more dramatically. The tilt as it appears doesn't strike me as intentional.
