Step 16: On the right side, draw the unicorn's other hind leg the same way but don't add the top part.
Step 17: On the left side of the body, draw a curved line for the top edge of the unicorn's tail. Below that, add a longer curved line for the bottom edge of the tail. On the left side, draw three short, spike-like lines for the tips of the tail.
Step 18: Using a pen or marker, carefully go over the lines to make your unicorn drawing permanent. After inking, get rid of every pencil mark with an eraser.
Final Step: Color your unicorn drawing using color pencils, markers or even crayons! You can color your drawing however you'd like. For this look, use pink on the mane, tail and hooves. For a gradient effect on the unicorn's eyes, color the top part dark blue and the bottom part light blue.
