Wonderful renderings. The only part that sticks out is that outside backgrounds look very bright or overexposed, compared to that the light in the interior is very less. They don't match. I understand it's one of the most difficult parts to match backgrounds in such renderings.
I think he was going for a photographic look, where exteriors are usually overexposed in order to get a well exposed interior. I think he could tone it down slightly though.
