Here's one of my favorite locations on Steven Universe: The Lunar Sea Spire.

I have recreated it in MC on MinecraftBuild.com hosted by Brawl.com. Not all of the spire is shown at once, along with the landscape around it so I took some creative liberties. I have used different reference pictures and shots from the episode with this present to get it's shape correctly and design.
(I do understand it's not 100% the same design-wise, especially on the outside. The structure and layout of the tower in the show doesn't make the most sense so I went with what would function better).

Steven Universe is a great show and I encourage you to watch it if you haven't. If you have watched it, here's a chunk of that universe for you to play with. I hope everyone enjoys it!
