Pretty sweet
Your ingame art seems stylistically different than this concept art, do you have different artists working on concepts and ingame assets? (mainly thinking about the general face proportions here).
I find something interesting going on with the black shading on the arms contrasting with the more classic painterly concept art style. It's quite small here and not something I've really noticed in your assets before, so I don't know if it's something you actively pursue, but as far as I'm concerned, that could be a striking/defining visual characteristic if you push it further.
As for the ingame assets, there's something that seems off to me about the eye placement, but maybe it's just a stylistic thing. I think it was also mentioned earlier that the black from Right Alice's overcoat blends in with her chest, making for a strange optical illusion. I see a small color difference when in full screen, but in medium/small size, it seems to be basically the same color.
I agree about the previous comments with the two sided Alice - a clear dividing line would work better in my eyes, with some clear elements that are cut (haircut is one, a more proeminent frontal implant could be another). As it stands, I had to do a few double takes before understanding it was two different halves!
