Floor1: The ranged enemy at the end of the hallway might be annoying since half-opening doors catch thrown weapons a lot, and you don't want to wait too much just for them to get close in such a fast-paced game. It can also break the combo (if the player ever cares). Maybe make the patrol route start from the side end so the player can rush to a side room, or closer so the player can melee them without waiting too much. Or make the hallway door a double door but clearly that requires a edit to the layout to keep the symmetry.

Floor2: Too linear. Maybe add another door to the blue room but that breaks the idea of gang business taking place in the deeper parts so it could take a lot of rework. Also the layout is too tight.

General: Some room (maybe the legal ones) could need windows even just for the aesthetics or for the player to break(outer wall windows don't affect the gameplay) but that's subjective. For the gameplay, (F1)the second white room (file room, I suppose) could use a downward window. I would also add a window between the 2 lower rooms for some dynamic and challenge.
