Great map, love the middle. :D
A few tippies:
1. Remove the signs that say "blue" and "red" and replace them with a red/blue lining or something. It doesn't look good to have words, looks a bit amateur.
2. The bases look a bit bland floorwise, potentially make a few decorations (pretty much last picture is a bit flat).
3. It feels a LOT like Skylands if you know the map besides the base layout and the island config, maybe mix it up a bit like add an under layer and no gravity killing (dunno if that is there or not).
Aaaanyways, nice job vwbay and goody! :)
