Has a certain solidity of composition, though I wonder if matching the line of the trees with the line of the tops of the grave markers is really effective. I understand the reasons for the tonlaity you've ended up with, and that sky is worth keeping the detail in, but it's led to a very flat and uninteresting tonality on the graves - which should surely be your point of interest here. There's a hint of the white lines of heavy sharpening here too.
Wonderful detail and composition. I like how the eye is led right down between the two rows on the lower left of the frame. The sky fits perfectly as well.
