Rock 'n' Roll Ninja Inked

Oh man... this took all night just to get perfect. I am super effin' proud of this little piece. I loved every second of it. I tried a lot of new things. I went outside my comfort zone, and challenged myself with a few new tricks, techniques and ideas. Little, small challenges, but the fact that I did them is big for me. I'm so happy with this, that I just feel like doing a million more. However, I've got a billion other things to do. Sleep, soon, is one. But yeah. I love this. Done in the gimp. Any CONSTRUCTIVE critiques are welcome.
*EDIT* The fullview robs this of it's glory... you can't even tell the texture I put on her shirt...
I might use this girl in some sort of story... if I ever get around to doing something like that. If so... she's copyrighted. By me.
