Quite an enjoyable vanilla map, with an intricate windy design and some cool secrets to find (found 6/10, my favourite was the SNG secret), which makes the map quite fun to explore.
I like the overall atmosphere and the combat is quite enjoyable, if not a bit on the easy side. The first yellow armor secret could've been a green armor, for example, to make things a bit harder.
My biggest gripe would probably be the overall feeling of roughness/jankiness when it comes to finishing, like in the brushwork/texturing, doors not telling that they're opened elsewhere, silent elevators, monster closet teleporters making noise (at least I think it was the monster closets that made the noise) etc.
Still, these flaws didn't detract much from my enjoyment, which is why I think I'd rate this map something like 3,5 or 3,75. Nice work!
