Step 11: On the right side, draw the unicorn's hind leg the same way as the first front leg. Use two long , vertical lines with a couple of shorter lines at the bottom for the hoof.
Step 12: Draw a long, horizontal line to create the unicorn's belly. To the left of the first hind leg, draw the second hind leg the same way as the first.
Step 13: Starting on the top, right side of the body, draw a long line that curves down for the unicorn's tail. At the end of the line, draw three short spikes for the tips of the tail. Now close off the shape of the tail using a long, curved line at the bottom.
Step 14: Using a pen or marker, carefully go over the lines to make your cartoon unicorn drawing permanent. After inking, get rid of every pencil mark with an eraser.
Final Step: Color your drawing using color pencils, markers or crayons! Color your cartoon unicorn however you'd like. I used yellow, pink and light green for a rainbow mane. The back of the mane is light blue, dark blue and purple. Use the same colors for the tail as well. Use light blue for the horn and pink for the hooves. Leave a strip on the hooves blank for shine. Add some light blue to the body for shadows. Add the blue mainly to the bottom and right edges of the unicorn's body. Don't forget to pause the video to draw at your own pace.
