Very cool to see the effort you put into the development process.
The striped would have very tough to animate, so I think you made the right choice there.
Also since she is a witch she can always magically dye her hair in a another cartoon if you continue with the character.
The the other color schemes could show up in another short of mirror dimension, or some such.
I must admit you made me think of an interesting idea, which is basically a "projected person. You can only see there body when looking at their hair, which constantly floats where it normally would be on a person, from a head on point of view.
So anytime their arm passes beyond the hair it is not visible, and a hair cut would mean the amount of the person who is visible reduces.
It's slightly odd idea, but I like to think about light and space alot.
Thanks for making this, and for sharing it
