I like #3 maybe because I'm more prone to higher contrast in B&Ws. Although, I wish there wasn't the huge black space in it. The second one looks out of focus?
I like the detail and contrast in it. I pretty much love all old shots like this is old houses and buildings. I have to go "hunting" around my area for some. By the way, I like them all, but the one does seem to be out of focus or something.
