Very nice, but it doesn't look like you've used Bluzone specific bricks...
But it is something that must be added to the Bluzone.
Could spring some events out too.
Uhh, not really?
There's more to the Bluzone than just events. Plus, the terrain provided would not be able to accommodate any form of airport. Perhaps a Helipad, but that's about it. There's nowhere near enough space for aircraft to take off/land.
