This is what it looked like after I got done poring over every milimeter of the drawing to clean up as many ink smudges as possible and ensure that there were no gaps in the lines. The three colors were chosen just to contrast as much as possible to keep the background, Fifi's outline and Fifi's insides separate. I filled in everything with black at the end as a way to clean up all the little leftover pixels and stuff, many of which ended up on there because I hadn't brushed away my eraser dust thoroughly enough. :(

Anyway, I thought this ended up looking bizarre and kinda neat by itself, so here it is.
