I always starve for more about mermaids' underwater homes, especially mermaid architecture that doesn't just look like the cliched Greek Atlantis or a photoshoped European castle underwater. This is brilliant! You're an amazing artist, and that structure is so beautiful and alien. It looks like something merfolk really would come up with. And you're an amazing artist to boot.
Holy balls, this is photomanip? DAMN. You're amazing.
