The hair looks great. The only suggestion I have is that (if possible) you should have that polka dotted texture follow her, and shrink when the camera moves away from her/vice versa. That way, you get the flat illustrated look, but you also get the feeling that she’s self contained and doesn’t have a head window to another static dimension. It retains the feeling of an object moving. The outlines are well done.
Yeah, I agree, the shrinking would be a better idea. Also if they were somehow flatly projected, but you could still move around them so they didn’t follow the camera. No idea how I would do that though.
Here’s a few of the Blends including the final character, as per requested in the vid comments.
