First map in this community where my first thought wasn't negative about except for asylum :)
Doing a quite good job, looks decent in my eyes for an AnD.
Also your texture in it is quite well it all fits and such, you have some nice details in it.
Only thing for you to improve is your lightning, you're using it quite well but some things:
-White light is barely good, use soft yellow.
-Light spots on walls are looking a bit weird, there is no lamp but there is light? You probably put them there just to make it look lighter, but think of somethings (first screenshot)
-The hall looks a bit weird with lightning to.
Like this (See difference).
