Hi!
I like your idea for your character already. As far as clothing goes, I have a hard time to pick as they all look cool to me. I think that last three looks a bit more interesting in terms of shapes, at least to me. Out of those C and D might be a bit better as the clothing leaves room for her arms can detach more freely.
As for the face, I also ahave apreference for C.
Great job so far and I'm looking forward to see your progress
