This is a nice piece. The white markings for lighting and hatching for shading stound out most to me. Her pose has an exciting energy about it. In addition to that, the color pallette works out really well. I assume that's saké she's drinking, but the composition really gives her an appearance of weightlessness, like she's in Zero-G or something. All in all a really fun piece and I'm interested to know how you did the color. It looks like watercolor to me.
