The only thing I'd really like that I can think of is for them to remove face types, and simply make the different nose/mouth/eye/horn variations interchangeable.

I love my fin horns, but don't like the fact that all of female Au Ra face 4's mouth options look serious, whereas the other faces all have at least one option that looks cheerful (Though I suppose that could be also be remedied by simply allowing your character's default expression to be changed, because my face looks fine to me when smirking/smiling).
