Bottle miku

I thought that she was cute so I decided to draw her =3 Jesus christ this was rigorous...
The coloring of miku is fine, but the background =_=; its unfinished but I quit, I don't know how to finish it. It took me a couple of days to try to finish it, but I was still kinda clueless, I need to practice backgrounds more. But I'll submit it just because I want to be done, I'll do another one of her later...
