Very interesting framing with the white sleeves and black hair. I'm not sure the lace/ see through is needed as the eyes/lips are immediate attention getters. The one thing I might suggest is to have her body twisted a bit looking as if she were turning around and catching sight of the viewer. This would take a series of shots until the right pose was captured.
Over all a beautiful image. I hope you will do some more work with this model (Maria.)
