Ok, this is something different from what i usually post here. A friend of mine sent me this absolutely awesome handbook about the Simpsons. It covers all the aspects of drawing the famous cartoon heroes from a scratch, all the motion details, the typical Simpsons environment (the bar, the street, etc.).
Awesome handbook by Matt Groening, the creator of the Simpsons. I hope he won’t punish me if I share it with you. You can always buy it if you like of course.
