Frankie, I recommend losing the vulture and maybe 1 or 2 of the bats. It seems a bit crowded there. The vulture is a large bird...much larger than a crow, and they are on the same tree. The scale is off.
The bat in front of the moon is perfectly positioned, but you can see through him.
That's an excellent creepy house.
On the gravestones, I recommend a few bits of grass in front of them, so they look like they are in the grass rather than on it. Maybe a few bits of grass in front of the skull too, so it looks like it's been there a while.
