not sure if it's intentional but the grain and washed-out lighting of this remind me of a very old postcard. it's a nice effect and even if you didn't mean to do it it's helping your score!
An impressionistic treatment. I get the impression that this would look a lot better if you were allowed to show it with larger dimensions. It just doesn't work with the 640 constraint. There's not much you can do about this though (other than enter another picture!), but I can't imagine the missing detail. 7
