I've looked at it several times now and don't know. It's certainly technically OK, nice play of lines w/o distortion taking you from the headstone to the tower, into the sky, the right toning but somehow I still can't "connect" to the picture. Only explanation I can come up with is that there are a lot of unconnected different texture areas in there. Maybe too much distraction from the main subject or so. Hope this little ramble helps, if not just forget it
EDIT: afterthougt: did you try the same from a step to the left, so the background is essentially the same but the headstone slightly more off-center? That's probably how I would have taken a scene like this. Just a thought.
