Aside from simply wanting to know how to do it I can't fathom why you'd want to. I'm trying to get away from it (and failing, woo like so much else) and wanting to do a bit more realism far as skin and stuff goes.
Ok posted the latest up. I got at least halfway between comic style shading and realism! XD I have found that I am actually just not stopping and making the shading defined, and blurring it instead. That is the trick to my realism style I guess.
