Presenting my Warhammer 40K "count as" Chaos Daemons Tzeentch army, with 95% conversions.
My Chaos Daemons army is easily the craziest modeling project I've ever embarked upon. All but one model in the entire army have some sort of conversion work, and many involved extensive conversions. The theme behind the army is a space marine force gone horribly wrong. It's what happens to space marines when they pass their expiration dates.
