I have found some things I am not happy about and think they need more work.
I don't like the area below his ear on the right hand side and also the shadow side of his face on the right hand side also. I will need to go over those areas with a light color and then paint them a little cleaner. On the face I need to match the shape of the other side.
If I go with the shirt I think I may have to add a little context to the background as well but that I am not sure about yet. I guess it will depend on the shirt.
