This is a island based on the Air Temple Island from Avatar.
It includes the island itself, a pathway from the beach to the town and a secret underground battle arena.
I used different biomes around the trees to get some leaf color variation.

As of right now I am NOT planning on finishing this build. I basicly made a good template for an other builder, who is more specialized in architecture, to finish it of.

So if you like it so far and think you can continiue to make the reference picture, please feel free to do so.
If so please just let me know how it turned out and credit where credits due ;)

This is realy not my best work but I gave it a shot.
It was made in a single day.

EDIT: Link to a project of Samv25 who made the matching buildings on top of this terrein:

Additional Notes

Made with the WorldPainter program and edited in game.
For some trees I used InHaze's Build Commands and the others come from the Fantasy Tree Reposatory by Lentebriesje.
