I would still add more detail to the grey parts. A couple of layers of textures on them would do them good. Grain, bumps and cracks and such.
This detail can then be enhanced by giving them a good fine rubbing with a shading and lighting brush.
The lens flares in the background are funny. It gives me the impression it was placed quickly to get a nice effect.
