As a very young girl, Siobhan began drawing the normal subjects. Trees, horses, a single eye staring back at you. She kept drawing, even when other kids started to put down their pencils. More trees, more horses, more lone eyes with overdrawn lashes and spiky iris patterns. Then she kind of grew up, and kind of got a career. But she quit that career so she could keep drawing. Now a professional, published illustrator, she can draw two eyes at a time.
