Well, I'll have to redo my screenshots, I think. I kept hitting prntscrn instead of the screenshot key. x_x Mostly, these were to point out where some of the geometry isn't quite right. Some pieces stick out in odd places at odd angles, and I've been curious as to why, because they don't seem to belong where they are for any reason. Hopefully the polishing took care of most of it. However there is one hall that is connected to a detention area model that overlaps a bit in an ugly way.
I've also noticed your conference room has a transparent ceiling. Now I'll have to check mine out, too. Only, with yours it's a bit more obvious because that cover piece you used for the doorway is so tall, and I can see what appears to be a second ceiling, which I'm supposing prevents anyone looking into space. I've noticed the transparency while working with the model in ZE, but I hadn't been able to tell it was like that ingame until now aside from what it does to the CP hologram.
That's a nice idea to use teleports. I just wish one area was distinguished in some way because it took me travelling through the teleports several times like an idiot to realize what was going on. I was so confused by it that I kept wondering why I kept reappearing in the same room, and continued running back to the other room to see if I was just losing it or if you were just playing a cruel joke.

Also, not to be too critical of the door in the destination room, but maybe it could be moved so it appears to slide into the doorframe, because it currently appears to slide along the wall.
Oh, and I do like what was done for what was the engine room on the ISD. That'll be a fun surprise for MP. "Let's blow the engines!" *Rebel pilots charge through the engine room doors* "Wait a minute...it's a trap!" XD
Btw, I think your Y-wing's normal flying or boost sound is bugged. I'll have to check it again to be sure, but I noticed this more than once while running around as an Imperial. It seemed like it was trying to play the same sound twice with only a slight delay, or somesuch. It's sort of like my Y-wing's turret fire sound bug.
I'm going to just throw this out there, but the comms array on the second ISD just seems to be in a very odd place. Well, it was odd in the stock game, too, but it really grabs my attention now. Then again, that's the canon-police side of me trying to come out again.
This is just the first playthrough I've done, but I want to get this out there before I forget it. I'd decided to take a quick look during my lunch break, which was about 7 hours ago.
