All the interior sets of imperial ships, especially the crashed one in S1 were absolutely gorgeous. The shiny black glass surfaces, analogue controls, blinking lights and fixtures everywhere were just wow. I can't remember the last time I saw such a well done rendition of "sleek retro-futuristic" aesthetic.
Part of the design esthetic is that nothing is labeled. How do people know that the 2nd switch from the right opens communications? I think that in the Empire you have to be a fast learner.
