Ok then, here's the texture that I consider my best, although I made it quite some time ago.
It's shown at actual size, and also painted at that size. I was going for a Quake 3 kinda style, but I still haven't been able to quite get there. I'm certainly no Kenneth Scott!
IMHO, the character textures in Quake 3 should be required studying for anyone looking to do hand-painted diffuse only characters. In fact, I'd say it's worth getting just to break open the game files and look at the texture flats! It's cheap these days anyways.
