Here are some drawings I've done using ink, graphite and charcoal.
I drew the image on the left as a submission for a mug design for the Riverwest Co-Op Grocery and Cafe in Milwaukee. The hairy horned monster is a character I have a habit of sketching, but I made the stick guy specifically for this. They are named Lignum and Pilorum and are vegetarians who love co-ops. (The design was not selected for the mug.)
