Rick Parker has had his cartooning work published in the New York Times or by Marvel Comics, and he brought those skills to the Millburn Public Library Wednesday. The Maplewood resident showed a group of middle school-aged kids the basics in how to draw a cartoon person, which he said was one of the most important things to learn in cartooning. Among other things, he showed them how to make their characters show different types of emotions through their eyes and other facial features.
