Very interesting subject and I think the B&W fits it well. The two faces of the building having such a discrepancy of lighting helps to emphasize the sharpness of the building's facade.
The image draws the eye upward so I find it incongruent with your title. The photo is washed out, but the light and shadow at the front edges is really quite nice. I think that should be your focal point. Interesting angle, but the image doesn't seem complete. I would try cropping it a variety of ways. I am not sure what would be best; I would want to play with it a bit. I think it is the way the trees are cut in half that gives it an unfinished look.
