I recently read a cool article from Wired magazine titled "What Caricatures Can Teach Us About Facial Recognition" by Ben Austen.

For the article, the author had several caricature artists draw him in their own style. I'm in a Type, Image, and Visual Continuity class right now and we're designing magazines so I wanted to use this article. We had to create our own imagery, so I decided to add my own caricature into the mix! The Einstein caricature I did earlier was for the magazine's cover, and this one is for my feature spread. To see the other caricatures, go read the article!
