First of all, congratulations on such a beautiful yet simple piece. The black and white effect give such a deep and sorrowful feeling, which helps with the slightly sad expression on the face. She also seems so lost and helpless- due to the mouth and eyes. The black on the lips make her look pale and lifeless, as if she's just draining away, day by day. The eyes are extremely thoughtful, giving a feeling that she either just wants to give up or perhaps find a way to get away- get away from her current problem. The darker shade under the eyes give her a tired look, which gives the effect that she has been feeling this sorrow for a while. The messy hair frames the face extremely well, and the fact she is bare- like all emotion has been drained- completes the look. Amazing work. Bravo.
