I like this one more too. I think the rail in the back is solid and not broken up, though. I also wouldn't put it past JJ to have only 1 turbolift going to the bridge.
If you looks between Kirk and bones (just to the right of Kirk's injured hand) there is a clear space where the rail should be, but isn't. So I think it ends somewhere behind Kirk's chair, then is back for the hostess. That's my theory anyway.
Gotta disagree with your camera placement for the crew photo, ancient. To the left of Chekov it appears we can see part of the helm console, with what might be Sulu's pop-up scanner sticking up.
Uh oh, you could be right. I'll look into it...
