It reminds me of a lot of pictures of London in the late 70s - early 80s I've seen: many were in b/w anyway. I love that slightly surreal atmosphere to it, and I think b/w was definitely the best choice!

There's also a punk feel to it, don't you think? Reminds me of a scene in "Johnny Suede" when Johnny encounters Freak Storm, aka Nick Cave in an urban backyard....
