Here’s a character from The Marzipan Pig. Tissa David animated the entire film, herself, and did a caricature of herself with this woman whose purse is stolen by an owl.
This shows Tissa's rough and the final drawing as it was hand-colored and mounted on a cel.
Stephan MacQuignon colored the drawing and Robert Marianetti added shading. Christine O’Neill did the cut and paste on the drawing to cel operation.
