Sweet linework here. i'm loving your style, and her [duckface] expression. Such a sassy lady~ I'm super in love with that left hand, I find it to be very well done and understood.
As for a bit of critique/suggestions, while the anatomy seems pretty well done, especially for this difficult angle, that right leg that transitions into the hip is a bit too sharp and makes her leg look awkward because of the angle of her foot. Another small design issue that I have is that her right arm is completely devoured by the black stripe adorning the background. It is a bit confusing to look at, it flattens her torso out. I understand that her arm is probably completely behind her but I think some suggestion of her arm or sleeve to separate it from the stripe would help a bit. Perhaps break the stripe up into two smaller stripes? Or perhaps pronounce her right shoulder a bit more so the fact that it is behind her looks a bit more convincing.
