I guess you can't go wrong with that. This piece certainly didn't! I really like the one in the back with his left hand reaching up, "NOOOOO!", he seems to say. A really creepy composition, and I imagine somebody's day is about to get VERY interesting.
After looking at so much art featuring undead, it gets easier to tell them apart. Not like that's a problem here, each of these guys practically BEGS for a backstory. I think that with any undead creature you should have some way of being able to infer it's history, that makes them so much more interesting.
