Step 6: Above the eye, draw long, curved line for the first part of the unicorn's mane. Add a small spike near the middle of the line for extra detail. The line should curve up on the right side. Draw a shorter curved line above, which is where the horn will peek through the mane.
Step 7: On top of the line, draw a triangle-like shape for the unicorn's horn. Draw it longer if you'd like. Add a couple of curved lines for detail. You can also skip this step to draw a regular horse.
Step 8: Behind the horn, draw a wavy line for the top of the mane. Don't overlap the lines for the unicorn's horn. Add a spike-like line on the left side.
Step 9: On the top left, side of the unicorn's head, draw a pointy arc with a line inside for the ear.
Step 10: Draw a long line on the left side and a short line on the right side for the neck.
