Sharpie and white-out on Chipotle bag. This turned out nicely, probably because the last project I worked on was about 3,000 "spontaneous" sketches for a math book. Gotta lotta practice drawing quick and accurate and weird the first time!
This was for the department pumpkin decorating contest, I whipped it out the morning of, using whiteout and a Sharpie. I cannot control when the muse strikes. ;-) I got first loser, second place.....Sorry, it's no DUNNY but what the hell.
