My Tin-Can Monster, Demon Erin M. First, you draw a can shape. The body will be green. Second, draw one small, pointed green hand on each side, but leave the tips white. Then, draw 2 slanted ovals and draw 2 big dots in the center of the ovals to be his eyes. Make thick eyebrows over the eyes. Next, draw 2 triangles to be the horns, a curvy tail and a spiny back coloured yellow. Then draw a frown with 4 teeth, that's his mouth. Draw 2 white wings on the spiny back. Add 2 legs and now Demon is finished. Have fun drawing him.
