actually not long at all... about 2 hours. I did it as a demo on vector art for my class. While I teach my class to primarily draw with the pen tool, I did this demo with the pencil tool to show them how you can get a looser, more expressive feel.
cool. I myself live by the pen tool. to me the pen tool IS illustrator. I can't really say that I have a lot of experience with the pencil tool sense I'm always tracing, but I'll definitely consider. gotta keep growing ya'know? lol
