Excellent! Simply as a proof-of-concept, this is a knock-out success; I love that whole idea of "skinned only with BTNs". Revolutionary. And
as per this discussion, I'm a massive fan of people collaborating & using
custom model's animation sets for their new custom models.
I will say, though, that I'd love to see a version of this done with a few standard in-game textures fudged in; there are sections of the armor & such (pauldrons, mace spikes, pants...) that seem a little cluttered/messy (just an unfortunate result of the icon, not your fault IMO).
Excellent work!
