I like how this looks a lot. It really looks like she is trying her best not to drop anything, yet is very worried she'll mess up. The colors and background express to me that the following result would be she would end up dropping them (since to be, dark colors=bad things to come....sometimes anyway).
Very great drawing!!! i love how you used it in your favor to make shadows, bubbles, hot lines, and other great tecniques. I also like the blurring on her cheeks and arms!! Keep it up!
