Very cute and appealing! Your sense of color is really strong; the color guides the eye very nicely.
Great shapes as well; I especially like how her eyelashes, ears and horns all combine into this sweeping shape to accent her eyes!
And personally, I love how her fang is drawn in that Felix The Cat way where it's combined with her lip. I'm a sucker for that.
The one area for improvement that jumps out at me: the shadows from her feet don't really make sense, given where the torch is. You might want to tweak that and add a shadow from her torso on the floor. Otherwise, the lighting adds some really solid color values!
