The first image is really good, but the second image (larger view) seems off... The view outside the window gives me the impression that its sunset and everything is a little darker than normal high noon sunlight, but the lighting inside the building doesn't quite match IMHO. Some of the shadows are off on the wall below the window I can't even see them they blend right into the wall.... Try reducing the photon intensity a little maybe? Or reposition or maybe even delete some lights where you don't need them. Is there a light source inside the building we don't see?
