i dig it... the look and tone of it are great!

i wonder if the hand holding the sword would be larger, considering foreshortening...

also, something about the breasts don't sit quite right with me. i think because the pectoral muscle would extend from the shoulder, it looks like her right breast is too far to her left and that her underarm rib area is too large...

or something... i am not sure if that is the exact reason it looks slightly off...

also, it took me a moment to realize the black was a mask and not something strange with her face. I wonder if there is a way to bring it out a bit more?

Those critiques and comments are in no way meant to suggest I do not think you have a strong piece here. The shape, pose, subtle shading, most everything looks really good.

Good luck on the competition!
