Very good
This is a very good drawing, so many people nowadays are computer artists, or photoshoppers, letting technology do the work for them, but you have stuck to the root of artistry, and that's something to be proud of. I like how you used the less is more approach with the hair, opting to leave it white in the center, you really manage to use negative space as well as positive. What I didn't like was the eyes, I found them to be fake and dull, and although it might have looked like that, there's no real feeling to them, nothing that gives them the qualities of eyes. All in all nice effort, nice work.
