disregarding the challenge theme, I think this could use a little more contrast and separation between the headstones and the grass/weeds. A different B/W conversion method may yield that. Also, a lower point of view may be a more interesting perspective. As it is, it's a decent shot (background sky is a little distracting), and the placement in the challenge is about what I would have guessed. BTW, thanks for commenting on one of my shots.
Good concept and great angles on the tombstones. Black and white is a good choice for this image. It might be even better if you increased the contrast in the image and gave it a true black point. Unfortunately the detail between the stones seems mottled and a little distracting to the overall image.
