when i saw this i was like woooooow that's awesome!
one thing i notice though, and i could be wrong, but the motif you're using of the wispy,smokey kind of lines that just seem to fade off and become indistinct, I think it could be much more brought out in the piece, you know, like maybe some of the other more finite lines could be loosened up and kind of swished in the same general directions to each other. But it all depends on what you're going for, because it would definitely change the style and representation of the piece. I just kind of feel a little bit like, with the beautiful, concrete, metallic shadowed style going on, those fading lines look a bit unfinished compared to the main style of the piece. They could maybe use some more 'essence blurring', and maybe some shading and refined sharpening.
Real cool indeed. Her outfit is amazing. Remind me a little Alita Battle Angel (Gunnm). The composition and the colors match greatly. I guess that just the line of the eyes is a little bit bent. But the work is real fine. Congratulations. ^_^
