Somehow I'm not surprised to see A in the lead so far as it's easily the first one I dismissed when looking at them.
For one thing, it immediately struck me as looking too bishoujo.
Secondly, the way she is holding the mace (arm straight out horizontally) makes it seem like weightless and insubstantial.
More importantly, the figure is relating to it like it was a functionless, costume prop.
The other three have their positives and slight drawbacks, but A is definitely the weakest of the four to me.
Therefore, congratulations- as I'm sure that's the one that'll make the final cut.
