Good things: the blotches on the headstone, the sawn off tree-branch, the angles on some of the gravestones, the sweep of the footpath, the cloud detail to the left of the church.
Might like to look at: dead space at the right (not sure anything right of the blotchy gravestone is useful to you), dead space at the top (where the branches interfere with the church roof), maybe some tonal variation in the B&W?
Atmospherically you want this to ooze negativity; cut out anything that doesn’t contribute
