This is my second go-around =) - I am not sure if it's just the resolution, but your picture looks like you've over-sharpened it. Otherwise, I really like your idea and the exposure looks perfect! Great choice for subject. Great job!!! I really like it a lot!
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 conversion. You have framed this well. The only thing I would change is to cloned out the two headstones in the front.
