I tried cropping on my screen, and I think it would be a bit stronger with a little taken off the bottom, probably to just below the upper cross-wise muntin bar on the window in the lower right. If you crop any more, you must leave some of that window (or clone it out), but there won't be enough to identify it as a window, so it will be a distraction.
I like the way the two roofs point toward each other.
