That's nice to hear, thank you for your feedback!
We have used an Hdri to light up the scene combined with some light planes.
Yes, exactly the animation was done in 24 fps.
Thanks for the reply! Would you mind posting up a link to where I can purchase the HDRI? Looks really clean/neutral without a colour cast (did you colour correct it?). I tend to shy away from HDRI's due to the colour cast issue (especially with white walls), generally sticking with Corona Sun + Sky which gives me quite a bit of control. That last render is epic - pure studio photo quality!
Re the animation I've found myself recently rendering at 30fps with fairly heavy motion blur then interpolating to 60fps in Resolve to get rid of the "juddering" that I sometimes get at 24fps on pan/zoom shots.
Well for most of the scenes we used an HDRI from "HDRI Hub" we don't color correct them we usually choose a cloudy one to avoid blue/purple overcast. In some separate scenes we used corona sun combined with an HDRI (the entry scene of animation and the bedroom-closet shot). Finally, in the living room we used an HDRI we created from a previous project called "5th floor apartment", could call it inception!

We had tried in the past slowing it down in After Effects mostly to avoid render time. Although personally I prefer 30 fps in compare to 60 fps cause it feels more cinematic.
