Everything is awesome: the base with dead trees and branches, the flesh colors from the horse and vampire wings, and the vampire's armor.
I only have one *minor* issue with the picture itself: the brown background doesn't really suit your scene. I would have used a black background, maybe with a red tint coming from below (but subtler than your brownish tint). Then again, what do I know? :P
What bits and models did you use? They don't look GW...
