A pretty nice map. Layout wise it's very open and most rooms have more than 2 entrances which is how it should be. The 3 entrances to the RVSF base vs the 4 entrances to CLA shouldn't pose too much issue but it's probably not ideal, not that I think you should change it now, it still flows well. Like Felix said, the paths do look a bit too cubic but it's not really your fault, honestly I don't think it looks much better in the screenshots he posted above.
Another thing about the snow I think you should definitely try is have bumps and heightfields. Currently 80% of the snow is on the same level as the concrete and top of boxes which doesn't make much sense; it should be raised. It might take a bit of fiddly work but it'll have a good effect in the end.
Good layout, good texture choices, the detail is pretty good from my perspective apart from what I first mentioned, nice job.
