Terrific work, RacerX!
This is how engineers do their work... actually putting the known factors together and doing "forensic" work of the sort you've just done. If it's not what you're doing now, well... it's worth bearing that in mind. You clearly have the two things that you need...
1) An analytical mind
2) A willingness to put preconceptions aside and make your conclusions based upon what you actually see, not what you were HOPING to see.
The only recommendation I might suggest would be to alter your "outer cylinder" for the bridge set so that the shell more closely fits the outer shape of the bridge interior. While I happen to think that you got it all placed nearly PERFECTLY, I also happen to think that there's more of a pressure-wall between the upper display ring and the bridge dome outer hull.
I'd also suggest that you might want to put in the two "red lights" to either side of the bridge dome. I've always imagined that those were sensors of some sort, rather than navigational lights, and thus would be the tips of vertically-mounted columns of equipment. But that's just my own personal predisposition.
Overall... very nice work, and I think it pretty much puts to bed the idea that the bridge should be in some other orientation. Jeffries clearly intended the cylinder on the outside to be the turbolift shaft, and he clearly fit the bridge set he came up with into the space he'd allotted in the ship design.
People can argue why the display was offset... and even say that they think it makes no sense... but there's no TECHNICAL reason it shouldn't have been that way, and there's an excellent technical reason that it SHOULD have been that way. Which, happily, you've just supported in 3D (something I've always had on my plate but just never taken the time to do!)
