Step 16: That’s it! You now have a nice sketch of Donatello. 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.
Step 17: For a more finished, inked look, carefully draw over the final sketch lines with a pen or marker. Wait for the ink to dry, and then get rid of every pencil mark with an eraser. You now have a finished inked drawing of Donatello! You can stop here or go to the final step to complete your Donatello drawing.
Final Step: For a completely finished Donatello drawing, you have to color it. You can use markers, color pencils or even crayons! His skin is green. You can use dark green on the side of his head to give him more dimension and volume. Color his eyes brown. Donatello's signature color is purple, so color his mask purple. The inside of is mouth is brown, and the tongue is pink. That’s it! You now have a completed drawing of Donatello from Teenage Mutant Ninja Turtles.
