I'm not sure how important lighting is to the accuracy of your recreation, but all of those coloured lights on the bridge are too much. Are you lighting the set solely from those coloured overhead lights?
From a quick observation (although I'm sure some diehard fan will know for a sure to correct me), it looks like the lighting on the bridge is from regular white spotlights in the center circle part of the roof facing across the opposite side to which they are on. I'm seeing a lot of top down shadows on those outer chairs in your renders. I don't think those coloured lights were strong enough to be casting shadows, and it's washing out some of your detail.
