A big part of being creative is relaxing your inhibitions. Below are a set of illustrations I made for an ESL class. Students need to be able to describe activities, use family vocabulary and give locations.
I am a big fan of Dinosaur Comics -where the artist uses the image, made from clipart, everyday- and XKCD, a comic made of stick figures. I think Randall, of XKCD has improved in his drawing, but he keeps his image as simple as possible and still convey his message.
