The map looks amazing overall and I hope it gets added soon in the game.
However, could you make some smaller islands in between the bases and mid/other bases (your choice, really) for fast travel (as in Airshow). That would make it easier to travel long distances without bridging a lot.
Also, I don't really know for sure if you will be adding that giant skeleton or statue but if you do, try to make the build limit low (people love camping) and also try to limit the number of any spots where camping is possible (usually around the enclosed spaces ,as in caves, of builds).
Please could you make a new thread with the pictures of mid (built completed) and the bases so that we can properly see them.
You are doing a great effort though.
