Great lines and a good subject for the challenge. A little over sharp.
Side note, there's just a little too much lost in the inky blackness in the bottom right. I tried it on 3 different monitors to make sure, then pulled a copy into Photoshop with a darker background and it lightened up just fine. The light grey does this all the time to B&W shots here, which is unfortunate, so maybe double check the appearance of darker areas after uploading in the future.
I remember a time when I would've looked at this and said "uh... meh." But I've developed an appreciation for more abstract art. I'm still incapable of producing any of it, but I can really appreciate it and this struck a chord for some reason. That said, in an effort to find something not to like about it, your title is uninspiring. :P
