A quick material node setup using procedural textures for pencil shading. I feel it is a decent 3D --> 2D look. Also I was told I needed to upload more stuff!! ;)
If anyone can show me how to get procedural textures to work with GLSL in view port, that would be GREAT, currently I cannot get it to, although images do work, just not procedural textures mapped via material nodes...
Inspiration from this blend--difference is I used nodes and slightly different method.

it would be awesome if those lines can be ratated(Duno if u understand). I have tried to make shader that render "natural hand move" pic but couldn't. U can always fake it with images but that's not ideal. Btw none of procedural work with glsl... but they do with cycles!!!
They can be contoured if you use UV unwrap and kill the camera vector. it takes a ton more time however.
looks really nice
