The sandy limestone look is really amazing ! Also, the presence of so many pottery in this tomb and the stonework screams ancient Egypt or Babylonian/Akkadian era so, I guess you nailed it. And, I won't say it again as I said it a lot before but, I'd love to read those maps and their stories compiled in a book (...). I know what you already said but I'd like to point to one of Guillaume Tavernier's project where he just drew maps with very little backstory (Borth and his Artbook). I'm convinced that with your amazing skillz, you'd not need much backstory, the maps tell themselves. But I won't say it again ... until next time
