Comsquare: Cool model, but I'm afraid it doesn't fit my view of a necromancer. Would work very well for a possesed warband though!
smokezombie: The fenryll ones were quite ok, but not exactly what I had in mind, still better thant the GW ones! The Mad puppet one is more like it!
I see a necromancer as someone that has secluded himself from the rest of society (often because you know, necromancy is illegal). Someone who has spent quite a bit travelling the wilderness and should have some tattered robes, while still looking like he commands power and is not just some poor old beggar.
