Wonderful.
Questions - are you leaving your coronasun at 1.0 intensity? I'm finding that in order to get a decent exposure in the main white interior space I need to whack the EV up quite high, which blows out the sun coming in badly, so I then use Highlight Compression to bring them down to compensate, but I'm then losing contrast in the overall image. Yours seem to have a very nice, soft balance but maintain contrast. Perhaps you're getting around this in post by blending exposures?
Are you desaturating your CoronaSun/environment/GI? It seems nice and cool. Almost no blue at all. Perhaps this is one key to the success of these.
One other question - your window glass. Anything special going on there?
Thanks,
