I think you've created quite a unique experience, something I could see being recreated as a real-life museum exhibition. I think the usage of real footage alongside the 3D graphics makes for a nuanced surrealism, one that feels authentically human and artificial at once.
Kudos for experimenting with hand-tracking and all these different techniques that we haven't seen in class yet. Maybe it would be nice to customize the doorways a little more to reflect the space we're about to enter? I would like to extract some meaning from this experience and not strictly wander around.
