Pendleton Ward, although not technically an illustrator, is most known for his creation Adventure Time, a Cartoon Network cartoon. He has also worked on The Misadventures of Flapjack series as well. I wanted to showcase his cartoon and illustrative work because of his style. It's very simple yet very expressive. Most of his figures and objects are drawn with simple lines. His coloring is flat. There are rarely any tonal renderings on his characters or objects. Eyes are expressed as circles or black dots. Mouths take very simple geometric forms, sometime mimicking the shapes of letters as seen in internet emoticons. Example: =C or D: or =O.
Even though his work is very simple, lacking much detail, and colorful, his characters come to life through their facial expressions and wacky poses. It really comes to show that the base of communicating emotion in a character doesn't lie in painstaking detail, but rather capturing the essence of the expression and movement of the person. For this, I think Pendleton Ward is an amazing illustrator, cartoonist, and animator.
