Very nice work. I love the back of the brown coat and his face is wonderfully shaded with pink/purple. I agree with FF about the metal, could probably do with some shading. My personal comment would be on the right leg of the trousers. It may be the angle of the photo not letting me see a crease that's there, and if so ignore it, but it stands out as a little strange because you've got the highlights at the sides of the leg and the darker colour on the top, but normally I would expect it to be the other way round. Can't wait to see the rest now!
