I'm in two minds about this one. On the one side it's a good, clean image. On the other, there's nothing which really makes it stand out, and, without the title, there's no direct link to the challenge theme unless I already knew what the building was.
Great shot, but without the title, I wouldn't have known it was the Holocaust Memorial Center. Love the fact that it's a "gloomy" day. Adds to the feel.
