Step 10: Under the polar bear's nose, draw a line that angles to the right for the mouth. Use short strokes for fur. The bear's mouth almost touches the edge of the initial circle on the left. Extend the line to the right too but don't make it as long. Below the mouth, draw a few curved, horizontal lines for the lower lip.
Step 11: Draw a couple of curved lines made up of short strokes along the edge of the initial circle for fur. Below that, draw another curved line made up of short strokes for the furry chin.
Step 12: Darken the right edge of the small circle for the first part of the polar bear's muzzle. At the top, draw a line that extends almost to the eye on the right for the bridge of the nose. To the left of the nose, near the edge of the initial circle, draw a curved line made up of short strokes to finish the bear's muzzle.
Step 13: Use the small arc on the top, right side of the head as a guide to draw the bear's first ear. Use a series of tiny strokes along the path of the arc to create the furry shape of the ear. Draw short strokes at the bottom for the base of the polar bear's ear. Add longer strokes inside for the fur found there.
Step 14: Use the small arc on the right as a guide to draw the polar bear's other ear the same way. First darken the path of the arc using short strokes. Then add more strokes inside for the detail on the base and fur.
