While this is a fairly decent design, I've learned so much more about character design and drawing in general since then. I started doing a bunch of sketches of Audrey (along with her lovable sidekick, Corridor Green), and I realized that my previous design wasn't quite adequate to represent her character fully.
Also, I realized that I wanted her design to be more focused on circles and spirals, not straight lines like in my original turnaround drawings. So I attempted to push those aspects some more, and I came up with this:
What do you think of this new direction for Audrey? Could you see her as the main character in a graphic novel or webcomic?
