What’s behind the door in this fantasy LEGO build?

This LEGO creation from Joe (jnj_bricks) was created for the Summer Joust 2021 contest, and it’s wonderfully moody. There are plenty of unique parts used here (see if you can spot the shark head), and the lighting is top-notch. The highlight of the build to me is the brickwork on the wall; it helps tell a story about this building and a lot of work clearly went into it. Another aspect that works really well is allowing the viewer to fill in the rest of the room by having it focused on the door and not having everything self-contained.
