I have added some detail to the girl's hair but will need to add a few more refinements at a later stage. I have adjusted the hand which is in front of the girl. This hand belongs to the lady who is to the left of the girl and will be lit by the light from above. I will then soften the edges and make the girls hair come over the hand which will add dimension. I am considering the tones of the lady's back, behind the girl, so that I can soften the back of the girl also. This will, not only add dimension but stop a feeling that the girl is 'superimposed' or 'stuck' on top of the scene.
