This is amazing, really well done. Excellent work.

With so much ambient light, are grain or blotches a problem? I dont see any of it on your images, so I see you took good care of it. :-)

What about transparency on the windows? In your renders the windows appear as white. Could you have transparency on them and see the outside?

What about other light sources? You say that these images were produced just with ambient light. Could we put a lamp additionally in the room, for example, without spoiling the effect?

What about Poser figures in these rooms? Do they look good in this light? Namely, have you tried a Poser figure with SkinVue applied to it? Or a Poser figure rendered with the Poser shader tree?

What about caustics, like from glass or water? Do they look good in this light?

Sorry, too many questions! :-) But your product did trigger my curiosity. :-)

I got curious about the SketchUp - OBJ converter. That is only necessary for the free SketchUp version, right? I ask because Vue can directly open SKP files from the pro version. Or does this converter do something else, like cleaning the mesh or something else? (SKP meshes seem a bit "chaotic" to me, in terms of topology)
