Visit Atlantis World's Fair 1938

I was at a loss as to what to do for Mythical Realms challenge. I decided on Atlantis, and this is what I got. I really didn't expect to get a good result in the challenge, because I didn't have a clear idea what to do, and because I saw so many amazing entries. Still, I liked it, and really that's what makes this so enjoyable. If I like it, and I get to share it, that's fun.
