Not bad! Your drawing style here is very cute and your line work is pretty good. However, your symmetry here could be better. For example, her leg in the evil side of the drawing is shorter and fatter than her leg on the good side. Also, everything from the waist down is further down on the evil side. Finally, her shoulder on the evil side is pointy and badly drawn.
I think maybe you wouldn't have had so many symmetrical issues if the line separating her good and bad sides was a straight line, not all curvy. Either way, you had a problem with making some things symmetrical here. Everything else was perfectly fine, though, and made for a good drawing.
