In an effort to find something more appealing, I'm trying a new design.
I also want to do one more iteration, to consider which style I find the most flexible for animation, and ease of lighting in the toon render... as well as just general appeal.
I found this design gave me immediate appealing looks with minimum work. All I did was rotate the camera around and move the eyes. It might be worth building a few face shapes to help her express, and see if I can make her emote.
