Excellent design and artistic concept. I have two technical comments:
1) Bevel your edges. I have literally said this dozens of times to 3D artists on NG, so it's not personal, but the infinitely-sharp edges on a perfect cube created in 3D software is one of the first give-aways that it isn't realistic.
2) Along the same lines, you have to make sure any curved surfaces have a LOT of edges and vertices, or you can see that the curved surface is really a polygon. That's another realism-killer. I'm looking specifically at the mid-right, where the display window curves toward the back wall. In full-size, it's obvious that it's made of 7 segments; increase that to 20 and it won't be noticeable.
But it's good stuff, and I'm glad to see all your posts.
