Looks good, but does it make sense based on the outside look of the building? But really the logistics of that building are already off.

I dont think we see this part of the building

Your hallway is still a bit too blue, even with addition of windows. The photons from the sunlight should dominate the hall, making it more white like everything else.

It might. I thought that the hallway was in a shadow part of the building since the sun hits from behind but in front of our characters. Adds variation.

Edit: Or there:

The top of the building it gives some reason/explanation so the hall behind lando is not a big set with no structure :)
