Funny you should mention that about the texture in my avatar. That is an image I did a long time ago and after I decided to use it for my avatar I realized it wasn't in my gallery here. But then I also realized it looks pretty chintzy at any reasonably large size (see image). I am currently in the process of re-doing it at a higher resolution for display here. Unfortunately the main texture on the head doesn't scale up very nicely. I've been going through a lot of what you are involved in with my efforts to try to recreate it from 2D Photoshop textures. Not too successful so far but I think I am learning some things from this thread that might help me. So... we will learn together!
