Step 16: Jack has very messy hair so the front part of the hair on the right side should be made up of lines going in different directions. The short lines move across the top of the eyebrow toward the edge of the main circle. Use different sized lines to indicate the choppiness of the hair.
Step 17: Now draw the top part of the hair. Follow the basic path of the main circle as you draw the left side of the hair using a a series of curved lines. When you get to the very top of the hair, use a few spikes to give Jack a kind of bedhead look.
Step 18: Continue drawing a couple more spikes at the top and finish the right side of the head by using the right edge of the main circle as a guide. Draw a few more curved lines of different sizes within the shape of the head to give the hair more texture and volume. Don't draw every individual hair strand just a few lines for detail.
Step 19: That’s it! You now have a nice sketch of Jack Frost. 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 20: For a more finished, inked look, carefully go 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 Jack Frost! You can stop here or go to the final step to complete your Jack Frost drawing.
Final Step: For a completely finished Jack Frost drawing, you have to color it. You can use markers, color pencils or even crayons! Color his eye gray. Vary the pressure on your crayon or colored pencil to get different shades of gray. Color his skin peach. If you don't have peach improvise and use yellow-orange or light brown. If you'd like you can add a some light brown around the eyes and lips for a bit of shading. The eyebrows are brown and his eyes are blue. That’s it! You now have a completed drawing of Jack Frost from the DreamWorks' Rise of the Guardians.
