I really love Scott McCloud's avatar design... I decided I needed to try to nail down a more consistent render of my own noggin. That's me above, sleeping in front of the computer in our old apartment, cooking spagetti (it was a REALLY good day) and scanning a sketchbook
There is nothing wrong with copying... it is the shortest path to understanding.
Designs for a dog snack and I'm not sure even I can understand this day's comic (actually I'm not sure I want to).
