Very Nice work! You only need to work on your beginning outline and softening your lines. The bridge of the nose looks as if you drew two straight lines and blended them in a up and down motion, same with the cheek lines. However, I am proud that you have attempted the mouth. I don't think that I could bring myself to draw something that difficult. Keep drawing, and don't give up, you will get better so fast if you try to draw everyday!
