A very quick doodle of Superdeformed Starscream, using my personal 'chibisketch' rules:
1) You must use an ink pen - no going back to cover up lines you don't want.
2) You may not work in a space larger than three inches square - so use the space wisely.
3) You may not take more than one minute to draw the picture, so draw from your heart and not your head.
For those of you not in the know, 'Chibi' is the Japanese word for "small/cute"... often referred to as "superdeformed."
