Step 21: For a more finished, inked look, carefully draw over the final sketch lines with a pen or marker. Don't ink the wing if you plan on coloring your drawing. Wait for any ink to dry, and then erase your pencil marks. You now have a finished inked drawing of a Cosmo! You can stop here or go to the final step to complete your Cosmo drawing in its entirety.
Final Step: For a completely finished Cosmo drawing, you have to color it. You can use anything you want: markers, color pencils or even crayons! Color Cosmo's hair and eyes yellow-green. His crown and the star on the wand are yellow. His tie, legs and the base of the wand are black. Re-draw his wing using light blue. His skin is a peach color. If you don’t have peach, improvise and use light orange or light brown. That’s it! You now have a completed drawing of a Timmy Turner's fairy godfather, Cosmo Fairywinkle Cosma, from the Fairly OddParents.
