Deepening the darks, setting up for opportunities of light and shadow shapes, telling the story with mood.  I look for areas of opportunities..how the flowers flatten on the shoulder and caste a shadow over the shoulder which describe that volumne as round...how the light on those flowers creates a curve which repeats the curves around the silohuette.  Repeated fractal curves, shapes moving in and out of the light, sharp shadows and soft caste shadows which give the figure interest and texture with values.  Almost done before moving into color, but want to do a few more things before that leap into hyperspace...I can see where I have been influenced by the way a sculpture is lit at the museums, and all the sketching I've done in museums overseas (Europe:  France, Spain, Eastern Europe).
