Converted from several diff. minatures... the chariot is a very old GW model, the horses are by Eureka, and so is the face-mask, the Tomb-king is a Reaper mummy lord.
This one is good, the "conversion" is brilliant!! I would have given it an 8 or 9, except the contrast black/white in the skeleton parts is a bit too stark - I think less contrast (brighter darks, or darker brights, whicever) would work better.
