lookin at the portraits, might wanna add a blue stripe to barbarians face in the skin.... it'd look a lot cooler. Or maybe, scrap that and skin a grunt, the axe might fit the character a little more. Also, i'd think the warlock would be a good model for a necromancer, skinned, and with a skull on the shield.
I actually made a darkpaladin skin, which is pretty much a paladin with skull on belt, black book with silver instead of gold on it, older lookin clothes, whiter skin, and blood tears rollin his face, which looks really cool.
If you want to check it out, e-mail me, could come in use for a boss, or the necromancer.
Also, remember, the generic Necromancer model and skin is awesome. Might not be very generic, but it works maybe better than anything else.
[email protected] is e-mail btw.
