Hey Spry, thanks so much for this wonderful response! Your comparision with Graffiti is a very good one, I like that. As you know my outlining is a essential part of my traditional art, an expressive one and I also like to use it from time to time within my illustrations, mixing realism with kinda comicbook lines, raising the expressive feeling... its hard to describe. So if I ever finish the Shaak Ti I sure will keep the white backlit outline but as said have to increase and develop the other things.
Cheers!
