For me, I would put 3 models into the undead section. The human model, with some decaying signs. The mage models, with the cloak, and skeletons.
And for dwarves put in a Dark Iron type and Windhammer (I know I am saying it wrong, but the flying dwarves) tattoes.
I also wish that Blizzard would help make your models really thin or fat, or affect the tallness a bit. It's impossible, but we can dream, can't we?
