Hey Howl, that's cool! So we probably have met during GDC then :) We'll most probably be around again with much more to show (including the big guy above and the boss fight itself). The proper shaders for the models are going to be applied through the game engine.
Charming, I like it. I do think you need some really nice shaders going on though to really push this cartoon look, because atm no matter how nice I feel this art is, it looks like its been dropped in a generic engine with no changes. Nothing too much, just a small change some how?
