Wow, that's a lot of models and textures! Good job, I don't think I would have the patience required these days to place that many distinct objects in a scene. I also like that you matched the outdoor (trees/hills) background lighting with overall scene (that is, the background clearly shows the direction of sunlight and why no light is beaming into the windows).
Those brownish (not sure, is it 'taupe'?) chairs and couch really look nice, that was a great color choice.
