Here is a neat trick: Lightly draw another ellipse around the one you drew for the sun. Try to give it an equal distance from the sun all the way around. Next, draw the curved triangular shaped rays. Draw them from the light ellipse you just drew and them draw them up to the end of the light lines you drew in the last step. This will give your sun an extra cool iconic look and balance. Draw a little bump for his nose, and draw it in the center of his face. Draw a simple mouth by drawing an oval with the top cut off.
