Think about how the lighting works. Basic infinite lights aren't really right for an interior, even on this scale.

Seen 2001--the landing sequence at Clavius with the ferry-ship descending into the base, on the landing pad. There are quite a few observation galleries, with people visible.

You maybe don't need a 3D figure in the Airboss Station, but a simple transmapped rectangle, silhouette or picture, would help set the scale. And enough light to see it.

More control/observation/refuge points along the wall bases and maybe some places on the deck. Where's the emergency gear if there's an accident? Some of this stuff could be separate props, maybe even one or two items as promotional freebies.

Any clutter needs to be controlled, but this place looks almost unused.
