Thanks for your nice comments.

@manz
in this scene the only lightsources are these that you can see. 10 lamps and the lightsource at the ground below the grate.
This was done in Fryrender but Mawell is showing an identic result.
When i`ve textured the scene, maybe the wall on the righthandside will look more interesting.
If not, i will have to add something ;).

"Please dont think I am criticizing"

Absolutely no problem.
