I think this is pretty damn good so far!!! The only suggestion I would have to add, and I stress this is just a suggestion...You might wanna try adding a little noise overall to the entire scene. Just a slight bit. It will dirty up the textures just enough to take the edge off of it looking like a freshly rendered 3d look. It will also add a little more depth. Like I said it's just a suggestion, and completely up to your personal tastes. Well done so far :-)
