Starting to come together Anita.. only thing I would try now is adding some more color layers in the skin... some shades of red blue and bit of green.. very light shades will do it.

You have it started in the lips. If you look at the above real picture of her you will see her skin has light shades of red and blue/green. Add similar colors to your color map and you will notice the skin will become a lot more realistic.

The model right now still has a bit of a plastic skin feel.

Hope you understand what im trying to say.
