The light job is good- it portrays and gives a high essence the pain the subject is feeling because of the choices made. One can 'hear' his thoughts of 'Why did I do this?' 'How could I have made such a choice?' etc. Perhaps a little more work to give a very slight bit of the surroundings- is he in a room or outside, and what is in his approximate location, more of just really only hinted at- would increase the power of the piece in my view.
