When a young artist asked me for advice on drawing the human foot, I told him, "The first thing you must learn is how to take your shoe off, and then how to take your sock off, then prop your leg up carefully on your other knee, take a piece of paper, and draw your foot."
—Chuck Jones, quoted from "Chuck Reducks: Drawing On the Fun Side of Life"
"Every great artist must begin by learning to draw with the single line, and my advice to young animators is to learn how to live with that razor-sharp instrument or art. An artist who comes to me with eight or ten good drawings of the human figure in simple lines has a good chance of being hired. But I will tell the artist who comes with a bunch of drawings of Bugs Bunny to go back and learn how to draw the human body. An artist who knows that can learn how to draw ANYTHING, including Bugs Bunny."
