I love the feeling and colour of this tileset. Look at all those beautiful, untinted colours...
I think this graveyard could benefit from two things: 1) a broken headstone here or there and 2) a little bit more of a transition between headstone and grass. Everything else transitions really really nicely; roots to grass, stone to grass, grass to other grass, but the headstones feel a bit like they're just floating on top of the ground if you catch my meaning.
edit: sorry I keep forgetting this isn't the screenshot topic and these are mostly completed shot I can't help myself ;_;
