^^ :DThe idea itself, as stated above, contains a lot more potential than how you've built it. You should add:
• Better terraforming.
• More detail / size to the middle island.
• An overall better block palette.
i really like the map and the individual islands are perfect [unless it is a team map then they should be a bit bigger to fit a few more chests or at least from the view we had pictures you showed] but the middle island [again this is only from what i saw in the pictures] seems to lack chests which chests are a little bit important don't you think =DHope yoo like it.
