I would question the wisdom of forcing the crew to go through a machine shop to get from the lounge to the cockpit/escape pods. Or through the workshop to get to medical. Those seem to be high priority locations that you'd want more or less direct access to, not something you'd want to stumble over things in a workshop to get to in an emergency.
Finally, a map that respects the basic concept of a docking ring! Is there a particular reason you put the cockpit access corridor in the bow pylon rather than the aft pylon, without also exploiting the additional space in the wing?
Niiiiice, this is awesome. I hope you don't mind me using this as a layout for a roll20 star wars: edge of the empire rpg that I'm in. My character recently got himself a yt-2400 and having a layout like this would be so useful.
It's not a cargo-carrier. It's a courier, which specializes in small, easily-moved cargo and people transport. The medical facilities would be useful if the crew happened to need treatment on a long voyage. The galaxy is a dangerous place, full of pirates and creatures that can make having the proper medical facilities nearby a vital aspect of your mission.
