Interesting image you have here. I really enjoy how symmetrical it is and the dramatic shadows. As for some constructive critism, I'd try throwing it to black and white in photo shop and then jacking up the contrast for a different effect. After that, there's got to be a way to add grain in photoshop to give the image an "old" feeling.
I thought about that, and tried it as a square image before I posted. However, as my alignment was not as spot on as I wished, I felt that the square crop accentuated the off-centered-ness of the photo.
