I like this one. The B&W really enhances this for me. Nice use of framing. I keep looking all around the picture and my eye wanders towards the tower. Good job.
Image is very dark, which would work with a bit of mist. The extreme heavy shadows take away from the architecture of the building. Still, it is a nice building to know about, which is one of things I am getting out of the challenge. Have you tried using something like a fog filter on your camera, just to see what kind of an effect you might get?
