It's too bad that the monsters use the same animations... having more uniqueness to them than mere model and sounds would have been nice.
Also, right now, that model doesn't really look that threatening. Sure, it has a giant horse head, but it has no real way to attack. It's a famished man with no weapon of any kind and only a loincloth on. It needs a claw or something sharp, otherwise all it can do is pimp-slap you... unless you want to animate a headbutt. That would be pretty brutal, with that big horse head.
Oh man if you could make this sucker lower its head and charge you like a bull? :o
