OH MY GOD that unicorn! I wanted to try pretty much the same thing on a unicorn
once but didn't have the courage, so I tried to make the mane look like blue fire instead. It didn't not quite work the way I had hoped.
Also: everything else looks great, I especially love the flamey guy, the tentacle eye monster, and the metal golem. By the way, do you ever have nightmares at night after painting some of these terrifying creatures?
