Give it a go yourself! Here are the steps...
Start with the head
Begin with a circle - make sure it's big enough to fit a face on it!
Add a nose
Draw another circle inside and add a couple more for nostrils
Draw some eyes
Guess what? More circles! Woo!
Give her some eyebrows
Draw some slightly pointy sausages above Rubi's eyes
Draw a mouth
Keep a strip of white along the top for her teeth
Add an ear
Draw a squashed circle on the side of her face and put a squiggle inside it
Add some hair
Rubi's hair is basically two lumps on top of her head. Remember to give one of the lumps her signature hair flick!
Add a ponytail
A little bit under the ear, 2 curls on the other side and another flicky bit at the end
