Hi Xiste!
WOW! I think what you are showing here has never been done quite like this before, not with SweetHome only.
I have used the moving camera many times, as you know from watching my old video, but the retarding effect is awesome. Can't wait for your tutorial on this.
And I have tried to figure out how you made the shadows. I guess two renderings? Am I wrong?
The light is beautiful. Did you render with IBL only?
I like it that you are using some of my models

.
I understand this is a short excerpt. Looking forward to see the rest.
I see lots of nice things have happened here while I have been in childbirth and had twins. I will be more active in the future.
Wish you a lovely evening.
Cec
