Now I'll be brutally honest here, and I haven't played it, so this might not be completely relevant, but some sections just look needlessly huge. I personally think a large majority of the player spaces could be scaled down, especially the areas with little to no height variation (EG: Screen 4.)
The Intel rooms strike me as a Doublecross remash; no very creative, but could still be fun to play on. The Decal present there looks completely out of place, as by that point the guise of shipping has been lost completely.
The wooden huts in the first screenshot don't really make sense too much; they just seem to be blocking the space and making the moving of the shipping crates harder in a real-world kinda way. Other than that, the sightline in the first screen is pretty horrendous. Though I guess it's comparable to the bridge on Teufort, as it is essentially the same area.
The Vent system should, IMHO, be completely removed. I don't think many people enjoy fighting in Vents unless it's against headcrabs, if you know what I mean? Perhaps add a small Outside section to replace it - some form of parking lot or security checkpoint, or hell, even the truck loading bay?
Other than that, I believe this map has potential. Good job.
