Step 11: Tighten in the shapes for Bowser's eyes. Inside each eye, draw a series of circles within circles to represent his pupil, iris and glare.

Step 12: Behind the left eyebrow and on top of Bowser's snout, draw in the left horn, which is just a pair of curves that meet at a top point. Don't forget to give him a base for Bowser's horn.

Step 13: Draw in Bowser's hair using a big curve for the bottom part that sits on his head and a few spikes on top for that weird Mohawk look that this video game character has.

Step 14: Finish Bowser up by drawing in the right side of his face, which is just a line that connects his hair to his eyebrow and another that connects his eyebrow to his snout. Draw in the right horn, and again don't forget the little bit of base for Bowser's horn that's hiding behind his eyebrow.

Step 15: That's it! You now have a nice sketch of Bowser from Nintendo's Super Mario Brothers. You can stop at this quick drawing for a rough, sketchy look or go for a more finished look by continuing to the step below.
