Step 11: Draw the skull's two lower front teeth. The shapes are like the top ones but smaller and upside-down.

Step 12: Add two more teeth on each side. Remember to make them smaller. The shape of the teeth at the bottom is similar to the letter U because the top row of teeth overlap the bottom row.

Step 13: Add two more small U-shaped lines on each side for the last set of teeth.

Step 14: Draw a long curved line at the bottom for the skull's lower jaw. Draw the sides first as diagonal lines then the bottom part as a horizontal line.

Step 15: Draw short curved line on either end of the row of teeth for the inner section of the lower skull's jaw.
