It is really incredible that it's done in vector. It must be a lot of work there. You should write some kind of tutorial for us when it's finished to teach us how to work with all those details.
it's really easy, actually - no special technique. I just make a bunch of basic round / 90% round brush tips and draw like I normally would if I were using a pen set. When I link it displays a lot more blurry then it is...it's a lot more crisp on screen. Is should silk screen pretty well.
so it's mor like alot of lines, then completed segments? How do you color it? in photoshop- or just leaving it black&white.
