I have the internet presence of a hibernating tuatara...

I always felt super bad for the Atreides family having to give up that amazing wooden castle on Caladan when they moved to Arrakis.  I'm borrowing a little of that here, if nobody minds.  There's also a fair bit of the old Olla Podrida craft mall in Dallas, which was a cave of wonders made out of old wooden aircraft hangars.

This is all the usual inks and such on Strathmore 400-series Toned Gray paper, plus a bit of OpenCanvas on the interiors.
