Step 6: Below what you have so far, draw a long, wavy line for the top part of the dragon's open mouth. Sketch lightly at first and only darken the line when you bet the shape right. The line should extend farther to the right than the eye.

Step 7: Under the wavy line, draw a series of V-shaped lines for the dragon's top row of teeth. The teeth don't all have to be the same size. Try making them different sizes. Stop adding teeth when you're below the left tip of the eye.

Step 8: At the bottom, draw a long, curved line for the bottom part of the dragon's open mouth. Sketch lightly at first. When you get the shape right, darken the line. The left edge should be flat.

Step 9: On the left side, draw a small, triangular shape for a spike on the chin. To the right of the spike, draw a line that slopes to the right, and then curves up for the dragon's big lower jaw.

Step 10: On the right side of the dragon's open mouth, draw a small line for the skin that connects the jaws. Draw a series of small, triangular shapes along the bottom edge of the open mouth for more teeth.
