Step 6: Draw a long line underneath that's similar to a wide letter U for the shape of the open mouth. Pay attention to the size and position of the mouth relative to the top part of the muzzle. Inside the mouth, at the bottom, draw a curved line for the bottom lip and a few smaller lines for the gums.
Step 7: Near the bottom of the mouth, on either side, draw two long triangle- like shapes for the growling bear's lower canines. Between the canines, draw three shorter triangle- like shapes for the bottom row of teeth.
Step 8: Between the top and bottom rows of teeth, draw the tongue using a series of curved lines. You can skip this step if you don't have enough room between the teeth for the tongue.
Step 9: Starting next to the eye on the right, draw a long curved line that's made up of short strokes for the right side of the bear's head. The quick, short strokes represent fur. The bottom end of the side of the head should end next to the mouth.
Draw another curved line that's made up of jagged strokes on the left side for the other half of the head. The left side of the bear's head should be wider than the right side because of the perspective. Draw two short, curved horizontal lines above the eyes for the top of the head. Leave gaps on the sides for the ears.
Step 10: On the top, left side of the growling bear's head, draw a small, C-shaped line for the first ear. Add a few quick, short strokes within the shape of the ear for the fur. Add a similar shape, only smaller, on the top right side of the head for the other ear.
