To provide a contrasting opinion, i like B the least out of all three.
To me, B's pose says "look, I've got shapely curves, look at how sexy I am," while A is much more standing proud, like she's going to defeat you in battle. The raised leg is nice in C, but otherwise, it's not clear what she's trying to convey.
Anyhow, great mood in all of them and nice work on the character sheet!
