Start off with a basic curved shape for the Library Faerie's head. Divide her face into quarters, like the red lines show.
Add a pair of curved eyes just slightly above the horizontal line that divides the Library Faerie's face. The one that
is furthest from view (her left eye) should be slightly smaller.
Draw a guide for her torso, like so.
Using your guide, draw the shape of her upper body. Don't forget to connect the head and shoulders with a neck!
