Hello! Me, and @_BubbleGumChewer have made a SkyWars map that we call, "The End". I hope you like it! It took us a lot of planning! EDIT: New picture because it now has stuff under the islands! Official trailer :
Support, maybe some water falls of certain islands. If you have worldedit on creative, you are able to do it.
Yeah. The cornucopia is a little small, plus one layer thick. Maybe make it a tad bigger and a few blocks thicker. Good luck!
I suggest adding more than one layer to the islands in case you want more supplies to best get blocks there.
