You did a great job lucy. Darker darks, careful where you place them (the eye follows them through the pic so try to get the eye to move from upper left down through the pic with them) and distinguish the background by pushing it back a little (things in the distance get less detailed and grayer, in this case probably a tad darker and less focused) The only other thing is the symmetrical face. Faces are not <i>really</i> symmetrical. If you look at a photo of most anyone straight on you can cover half the face with your hand or a piece of paper or whatever, take a good look, then cover take your hand or the piece of paper and move it to the other side of the face and take a good look at the other half of the face. You'll find that the eyes are not identical and the other features are a little different from one half of the face to the other. Of course you might be doing the symmetrical thing on this panting on purpose for an effect, I don't know for sure, I'm not there. Good job.
