I was going for a more cuter look for Charlotte. For the design of the head, I looked at characters like Charlie from Hazbin Hotel for inspiration. So I made her eyes a bit bigger, gave a thinner neck and maybe simplified most of her look.

I also changed her attire a tiny bit. Sort of taking an idea my friend suggest that her hair should have and gave her a pink and green shirt. Maybe a wave bar of green on a pink shirt with navy blue jeans or something. (Just need to get a proper color scheme for these two when they break out of this prison.)
