Step 16: That's it! You now have a nice sketch of the Flash. 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 the Flash from Justice League Unlimited! You can stop here or go to the final step to complete your Flash drawing.

Final Step: For a completely finished Flash drawing, you have to color it. You can use markers, color pencils or even crayons! Color his mask red and the lightning bolt yellow. The Flash's skin is peach color, but if you don't have peach, improvise and use yellow-orange or light brown. Experiment! That's it! You now have a completed drawing of the Flash from Justice League Unlimited.
