As I look at it, I'm hunting for the subject. There's a lot going on in the image in terms of movement (not motion, mind you); lines leading this way and that. It's nice, perhaps a bit too heavy in the mid range of tones but the contrasts between light and dark elements and where they're placed is nice. If I wasn't provided the background of the image, I might guess that this was carefully staged with some thoughts to composition (perhaps it was?).
It's got a lot of things going for it, but it's also lacking a clear vision of what the subject is.
