Ok, here is not really a show of model skill, I just want to celebrate the fact that I finally decided to learn to make some custom textures, the sword I made in like 2 minutes, and the texture I made pretty quickly too, but, Im happy that I made a texture. I know its bad, but WOOOOOOOOOOOOT!!!
I think you could do something with the end of the mouth, it looks a little weird, I don't know what though, maybe try to round it out a bit. And the lower lip should be rounder as wel, I think. I hope you understand what I mean.
