Intriguing composition, entire image seems to be focused to high, like all the elements are pushing the eye off the top border. Maybe if the angle was a bit higher to create more of a gap between the boat and the dock.
I really liked the idea, and frankly struggled with my rating of this image. I feel that the warf and the boat are in competiion for my attention, with no defined subject. I find myself wishing that the warf could acecentuate the boat in some manor.
Good idea.
