I think as was pointed out, she is still in uncanny valley. It's a shame because you have put so much time and energy into rendering the face. But I do think the face form needs correcting. One tip which helped me a lot when I was learning traditional art was to think of the lips as just part of the face - mould and shape them as if they are clay with the cheeks - then finally just add a slight bit of colour

Kind of got the bottom half animated

I think it's quite boring and lumpy/ugly, and the palette doesn't harmonize well. The house on the left is my favourite. You should think of some more cool ideas to play with and really sell this game, as there isn't really anything here special or unique or particularly interesting.

Here are some random artworks which have inspired me. Pay attention to the palettes and composition of them, as well as the design features which make them interesting. Trying to shoot for a particular mood is one way to think about it - to keep focus, and keep things unified.

Hmm I think your rendering is going quite well, but your problem is not with the palette, it's with design. For example the two green beard shadow men are virtually identical, one is just looking 5 degrees to the right of the other.

I'd look at some more references and brainstorm some design ideas and push the ideas on these.
