Step 10: Draw a curved line over each eye to make the abominable snowman's brows thick. These curved lines should be made up of smaller angled lines to represent fur.
Step 11: Below the eyes, in the middle, draw two short, curved lines for the yeti's nose. Between these lines, draw two more small lines for the nostrils. Add a line below the nose too.
Step 12: Below the nose, draw a long, wavy line for the open mouth. The line should almost reach the bottom of the circle. Pay attention to the curves of the line. You can make the abominable snowman's mouth bigger if you'd like.
Step 13: Draw two triangular shapes on the outer edges of the top of the mouth for the yeti's canine teeth. Between the canines, draw three smaller triangles for the rest of the top teeth. Do the same thing at the bottom. First draw two big triangular shapes on the sides for canines. Then between the canines, draw three smaller triangles for the rest of the teeth.
Step 14: Draw a couple of lines on the sides to finish the mouth. Inside, draw some curved lines for the yeti's tongue.
