Hi Tony, cool details on the board.

If I may just say something, you should try to avoid multiple lights shadow (I count 3 shadows with different softness). Usually one shadow light is enough.
Btw here's a couple of hdr studio, that you can place as environment map (and maybe disable them from the camera view), and activate the radiosity.
So you can get nice reflection on the surfaces.

There maps are free, the author post them here:
