The Oatmeal is one of my favorite illustrators who uses his website to blog, and create various comics, satire pieces, and horrible holiday cards. A local Seattle resident, he goes by Matt and has been creating webcomics since 2009.

The artist Mike Mitchell is a great example of fun, twisted, and slightly off beat illustrations. I like looking at his designs due to their boldness, the uniqueness of the designs, and use of clever illustrations.

The third illustrator I like to turn to is Olly Moss. His designs are very distressed looking, independent of what most people consider the norm. He lives in the U.K.
