Made with Blender 2.65a, rendered in BI
Testing some unconventional lighting in Blender Internal.
One sun coming from behind the corner, two area lights facing each wall. No lights behind the windows, although I have some hidden on another layer and they look pretty sweet, I will probably add them later. Environment lighting on "White" and a setting of 1.2. One Soft Light mix node in the compositor. That's about it
