Another of your glorious video tutorials, Beat; very well done - as always - and thank you so much!
I notice you don't show your methods for "adding an appropriate natural depth in the room" or "panning", and yet these are of course the crux of presenting orchestral ensembles and instruments convincingly and attractively in the stereo field.
When you showed your Late Reflections (LR) algorithmic reverb plugin in the video, I wondered if you're using that same make of reverb plugin, together with its companion plugin, for Early Reflections (ER) spatialisation - i.e. using an apposite variety of Angle and Distance settings in the automatically-linked companion plugins? I can't say I'm altogether convinced I'm hearing in your video the option I've just described - though I'm willing to be wrong. I'm well aware from experience with this particular pair of plugins that it can be tricky to set up and many kinds of results are possible; but when it all comes good, oh heavens above, it's astoundingly good!
Alas, of course it wouldn't be appropriate to go into detail about these particular plugins in this forum, but if you could indicate in general terms if I'm on the right track or not with my guess above, I'd be very grateful.
