Colours are good, background too, since your style is already set in stone, the facial features, despite how much I like them, are too consistent, to be specific, the eyes. But I'm not an artist so you can throw this opinion away. Keep up the good work
It's a great piece of work. I have just one problem with it And since you requested a critique.. The black drop shadow effect around the figure works well in some areas, but, since you've outlined her entire figure with the same effect, it effectively flattens the image and robs it of depth. Some of those shadows around her lower body for instance, should be larger indicating the varied space between her legs and the billowing cape. And the shadow around her hair pins her head to the background. At least some of her hair should fade into the highlights. Other than that, it's really outstanding.
