I would hazard a guess that Mirek means that you cant really see anything.

I know its supposed to be a computer room at night, but as its at night you cant see much of the texturing work you've done on the models, so it sort of defeats the object of doing a textruing and lighting project then having it in the dark (other than the screen).

Personally I would change it into a computer room in the morning so you can see the textures and make a nice bright morning feeling.
