Another long delay and another update! All I've changed since the last render is the edge between the tunnel and the screen itself, making it look more a part of the TV now. That and I've moved the cart back a bit. I tried a version without it entirely but that seemed very bare to my eyes.
Same Quicktime as before but with the new entrance:

Once the sun comes out again I'll reshoot the background footage, keeping the room tidy of course

, with some kind of reaction to the bats as well. I have a lighting issue with the current footage. It was quite a dull day leaving everything looking fairly flat, hence I ramped up the contrast so much in the composite. I'd rather light it properly to start with this time and avoid too much correction as ultimately that is breaking the illusion a little imo.
