Wow... really just... wow. This picture is... amazing!
The head seems a bit flat (though that may just be me), the lips aren't quite centered, and the right eyebrow seems a tadbit awkward, but overall this piece is... AMAZING! I LOVE how you did the hair, and the eyes stand out just enough.... this is really a great picture, I LOVE your artwork.

You own everything that happened to you. Tell your stories. If people wanted you to write warmly about them, they should have behaved better. — Anne Lamott
