Step 6: Draw a wavy line under the mouth for the horse's lower jaw. This line should curve on the left to form the chin and again on the right to form the jaw.

Step 7: To the right of the horse's eyes, draw a thin, pointy arc for the first ear.

Step 8: To the left of the ear, draw a couple of curved horizontal lines for the front part of the cartoon horse's mane. The left end of the mane should have a few spikes for the tips.

Step 9: Draw the tip of the horse's other ear on top of the front part of the mane.

Step 10: Add the rest of the horse's mane by first drawing a V-shaped line between the ear and the jaw. Now starting at the ear, draw a long, curved line that slopes to the right for the top edge of the mane. Add a series of lines toward the jaw that are similar to curved letter V's for the lower tips of the mane.
