Like everyone else has said so far, I agree that something is missing in the photo, and the top of the photo should be cropped just a little. In my opinion I would said that the contrast on the black and white should be a little more. Other than that great concept.
There is much more detail and contrast in the barn than anywhere else, so I find the sky, trees and ground to be just distractions from the real image. Of course you have to include little of these, but I would crop tighter. This is a subject that demands closer shots of its parts. If you can go back, get closer and get more detail.
