I wouldn't go remapping from Glloydstation. It has two major design flaws (both of which I kinda blame myself - I didn't map it, but I pushed for them for novelty's sake) that could be directly replicated by copying over areas, both of which boil down to 'too big for our current pop' - which isn't bad in itself, but a new map could fill that niche.
First, the double-corridor design, which would be perfect for very high pop thanks to its throughput but on anything less than only-Assistant-slots-open-tier fullness makes it very easy for people to avoid each other when moving through the station, so our lowpops feel like nopops. It seems heavily reduced here, with it only circling the bridge a'la Boxstation, so that's a big plus, and another is that you're funneling people through the Bar, which <3
Second, the room sizes, pretty much the same effect as above - and they indirectly impact the map size, making it larger. I've always regarded BS12's mapping pulls talking about movement flow a bit un-seriously, but turns out it's way, way important. This seems largely untouched. We could use more compact rooms and leave the space, or maint to fill the space around with seekrits. Or maybe leave the lattice on the actual area - it would look kinda 'station in construction' and would make it easier to fill it out later in game or DM.
You need a straight connection from the arrivals corridor to the bridge corridor. Otherwise, looks good.
I'd cut out a path through the maint (just make it a room with N/S maint doors and W/E regular doors, like the tiny passages in Toxins or Viro) from that tiny indent next to IAA to the blue-white tiled area with the washing machines - the actual machines could be dropped into the toilets or something, since they lost their no. 1 use in the update - and make it a Command/Sec-access door or something along the lines so most people don't use it. See 1) above.
Another suggestion - take a page from Goon's Cogmap and move people from Arrivals straight to the bar by swapping out Arrivals with Cargo - this will shrink the path majority of the crew has to take to get to the station from Arrivals. Also also, bear in mind the update's features. Learn them. Use them. Love them.
