I made a skyloft inspired island! I used MCedit to terraform the island, did some touchups by hand, and added the forests with SPC.

There are many hidden places on the island, I'll put a list at the bottom if you want to find out where!
I also added a few buildings including a ruined tower near the bottom left edge of the island, and a house at the top of the incline!

Chiseled stone bricks mark the secret places (where digging is required)
Feel free to use this as a survival map, pvp map, or just to add your own stuff to, I don't care!

Additional Notes

Location of the secret places:
1. If you are facing the giant hill, on the right you will see a few planks leading down to an under-island area.
2. In the lake, there is a door that leads to a hidden area.
3. In the large pit, on the second ring from the bottom there is a digging block that leads to a minecart track.
4. on the wall itself, there is a digging block that leads to a lookout area.
5. by the house on the hill, next to the tree there is a trapdoor.
