Very nice.
~~REVIEW~~
ok so after seeing your other piece i thought i would checkout some more of your work, and this one i must say is pretty awsome if you ask me, now while its mostly in black and white thats an ok option but as you say nothing more can be done but i think a colored version, maybe not all collered but some, just even a tad, and i know her weapon is somewhat coloered but still goes with the black and white style, i would even go as far as have more glow and shine on the bacround so there is more glare comming from it, but other then that this was pretty good i thought.
~~THINGS TO IMPROVE ON~~
I suggested a few ideas above, some lighting effects for the moon, some color options and such.
