One teeny, tiny suggestion in what's otherwise an obviously fantastic work:
The access ladder from Deck 1 to Deck 2: why not make it one of those triangular access ladders we saw in various episodes? An example that immediately comes to mind is the ladder that Scotty and his crew use to get to Engineering on the Constellation
n after beaming over in "The Doomsday Machine":
Again, amazing job and I'm by no means against the ladder as it stands. It just seems to me that the triangular ladder might be a neat bit of continuity.
