This is my second go-around =) - Very nice! Excellent use of b&w, and contrast is perfect. I love it! I wish the crop was not so tight on the top of the tombstone, but still a great photo.
In my mind this lovely image suffers from too tight cropping at the top; I can see you tried to "help" it with the frame, and might have been able better to help it with a frame that was wider at the top than on the other 3 sides. It also, to me, lacks the sharpness I'd liek to see in the rendering of the subject stone. The overall softness may have been intentionalon your part, but I'd have masked out the leaning stone and used a good dose of USM on it I think.
I am making two passes on this Challenge. I will vote on your photo then return later(before voting is over) to comment on what I like and dislike about your shot. You can take the comments however you wish and I will try not to be mean. Just don't take it the wrong way.

Nice composition and nice conversion. Nothing I don't like. Bumping up.
