The shading is very beautiful, and I think the must stunning part is where the bangs fall in front of the eyes. And the ears - they are absolutely gorgeous. Hasty or no, this is great.
I love your style; it's very distinctive. And the coloring reminds me of...those color-trace sheets for animation cels (I'm probably using the wrong name. My point anyway is that it looks really good! ^_^;; ).
