hey ok, i just noticed a few things you might want to change to make your game better, not big things.
first i noticed how for some two-or-more level buildings you were using the same wall and it was very aparent that it couldnt be real(you dont have moss all of a sudden growing halfway up a building.
second, id add in some light sources, it seems like light is coming out of nowhere
third and final, if you use the flouresant lights, add another floor, because the player can walk into them or jump into them, just very unrealistic
other than those few things, it looks absolutly fine. good use of the "bioshock dude"
