Those horsemen look really sweet, but I had a suggestion/question.

Most of the pictures I've seen of Parthians and Scythians show them wearing that leather looking cap with the flaps on the ears. Should you be showing these horsemen wearing that? Also, would it be possible to use the basic Persian head for Sythian and Parthian units, but with lighter hair perhaps? These gaulish faces don't have the full beards which I understand the Scythians/Parhtians favoured.
