Good map layout, I like it… But it could do with some different textures.
For instance, (This one's a little personal, so no need to edit it, it's just my opinion.) I feel it should have a little less red checkered floor, walls, and ceiling. Maybe you could keep the floor, but make the walls and ceiling bare, like a regular hospital.
Also, you need to completely change the textures in the generator rooms. Think barren and musty, like a janitors closet. (I also think the doors in non-patient rooms should not have a window.)
Also, the glitchy safehouse door with nothing in it and you can't enter it should go, but that's it! Good work, and keep it up :)

Note: I'm not a maker like you guys, I'm just sugesting stuff.
