Lighting Large Interior Area's!!!

[jcsDesigns]

Hi All

Please see attached the visual I am working on, ignore the the maps ect, I know these need sorting. I am wanting to know how I can effectivley light the whole scene? at the moment I have a large vray light over the ceiling and the only other's are the uplighting on the face of the Mezz.

I need this scene to look very clean and interesting but I need to get the lighting sorted out first.

Any comment's or help would be very much appreciated.
