I'm glad you guys like it so far !
As for the hair and fire, I'll probably do it in real time, as I'm a bit lacking in the render departement ^^'
I'm a bit familiar with XGen on Maya though, so I may give it a try but I'm clueless as to how to render fire haha !
I was also thinking about molten lava instead of pure fire, I'm not entirely decided on the concept yet.
