Definitely an improvement. There's still something funky between floors here (see attachment). Not sure why all that is visible. Could also put some sort of wall behind the side windows to help block a lot of the middle area when you're at the back corners of the base.
Probably going to repeat myself here, but:
I love the streamlining you did around the ladders. I wish the stairs were also streamlined, but they seem even worse than the original. I think you could make some tweaks to streamline them but still keep the travel time slower. Using awkward layouts where you bump into stuff is really frustrating and is just going to make people hate the map. It's super annoying to hit your head on something then get shot. Could move the entry and exit points of the stairs a bit to lengthen the path.
Inside the flag area is a bit confusing. Maybe put a banner texture on the back side of the base so you know to go the other way to exit.
The ceiling texture looks out of place, since it's designed to be on a wall. Yeah, it's what was on the original, but most of the other textures got changed up anyway, so might as well change that, too.
I put the map up on the ev1 beta server so it can be playtested.
