I like this image a lot. The biggest thing I don't like about it is the fact I didn't take it. :) I would do a few adjustments to it. I would punch the contrast. In my opinion, strong black & white images are either: very black and white or have enough contrast in it to give a little emotion. The bright portion in the upper right corner needs to be toned down or a little vignette.
