Nice environment!
I would suggest making it less dark. Especially the last image, human eyes adapt to night time quite well and even in dimly lit city streets that have just one pitiful lamp post you can still see quite well and the light radius of the lamp appears quite large too.
Houses in flames I imagine would provide way better lighting than those cheap street lights!
Add some sky too, having a black colored sky is only a phenomenon observed in the heavily light pouted cities where you’d see one star at most. I don’t know if the light from the flames would make the scene too bright for our eyes to be able to see the sky, but it would just feel better. Make it blueish, and add a blue ambient light to your scene as well (From the sky and all). Orange contrasted with blue is a common thing in movie lighting.
((Also but only if you think it woudn’t hurt your performance too much, you can add soft shadows to your hallway scene, fires need blurry shadows))
