great title! i think i would have cropped out much of the trees and just focused on the tombstones. also i wonder how b&w would have looked - but good idea for the theme.
obviously lots of repeating elements, so really meets the challenge - but half the picture seems wasted - maybe you could have framed the grave stones higher to remove the trees/ focus on the pattern more ?
This could be much better if there top of the stones were about 1/3 from the top instead of 1/2. All the trees really take away from the shot.... You would want to RAISE your tripod and lower the camera angle so to keep the nice angle on the stones.
