1. Draw your base shapes and survey them, making sure it will help in shaping your sketch.
2. Trace around your base shapes, stopping often to look at your unicorn and making sure it looks how you want it to. You can rub out extra lines if you want to because when lining it, you might get confused with which lines go where. It helps!
3. Add the mane and tail accordingly! You can play around with the different styles, I quite like the traditional Unicorn style – with the lion-ish tail & long mane ouo

Hope you enjoy! The reason for this is my friend wanted to see how I did this stuff .__.
