The art is strikingly beautiful, but the design of the outfit is absurdly impractical for any kind of fight; this is a case where all the complaints about female armor are in full force. Aside from all the bared skin, why the empty loops in the skirt? That will catch a knee and make you fall over the moment you tried to move with any speed.
Between that and the posture, not to mention the expression and the way the weapon's being held, this doesn't give the impression of an actual fighting woman- it is very clearly a woman playing dress-up to look pretty.
Spot on, she's actually a fertility cult priestess, so the gear serves a purely cerimonial purpose (and that is also why she is so little dressed). I could have probably gone with a less silly pose, that's for sure.
