The beginning of the map is very good, if you kept the style of the beginning. But then it gets really boring

I know the map looks equally bad when it comes to leaks and low effort being putted in. But guess what, right now I'm working on a entirely improved version of it, in which some areas will be changed in terms of layouts, re-texturing in certain areas, new areas to explore, adding props, no more leaks, better lighting etc.

So keep an eye on that!

not a bad a map

Looks like places in my dream

Not a bad map. I think you should remove the outside if no one is supposed to access it. If not, making the outside look better and smoother would greatly help. (I see you already mentioned this)

I would recommend making the ceiling of most rooms higher (Pretty sure you shouldn't be able to bonk your head on ceiling lamps like IRL).

I also think some of the room layouts are weird, unless you are trying to go for a 'liminal space'.

Adding more props/details could help sell that feeling.

Daaaaaaaaaaamn! This map is kainda laminal and scary AF!

cool

didnt think much of this from the initial spawn but looking around the map, was pretty cool finding all the little rooms and how they were all connected, the water part connecting up to those rooms was pretty cool, even if it doesn't make sense physically.

if you added more detail overall i think that'd really make it fun to explore, as i was walking around i was connecting all the rooms up as i found them and trying to see the story of the building, what was the monitor room, the dead end hallway etc. tone down your lights also, way too blown out

should learn to properly seal and contain your map too, since it just looks like you have it boxed in skybox and are just fully texturing blocks when you're creating rooms, where you could use alot of no draw and really clean it up, keeping walls consistent size across map etc.
