That is one hell of a Quality jump.. Lighting is much better in that scene, a few tweaks to compensate for the outside (raining/dull) look; definately would really look awesome.
Lightmaps are bad in the sense that you cannot make a scene come to life; however good in the way it doesn't matter how many you put in a scene as it only slows down compliation time for the RAD. So don't be affraid to use a few to get given effects.
Remember there would be light comming in from outside too, it is often forgot about this; even when the sky is dark.. so you'd get a subtle grey/blue ambient. You then accentuate it using the internal lights.
But again a damn huge improvement from the other shots
(and the MP40 gives it a nice breath of authenticity
