I wonder how the building would have appeared if you used the mural side as the focal point. Building also seems a little tilted, but you might have been going for that effect. Great shot.
I think the angle strips a bit of detail from the windows - the window sills are very deep. This makes it seem like a very tall building, despite the fact that no wide-angle distortion is used, and the frame is horizontal. It's like one of those pictures of new york sky scrapers, making a face at the sun.
I really like the sharpness of the edges, and the textures, and the colors are simply brilliant.
