A few mini dioramas using some 6x6 flat tiles I got a while back. I love them; I'm definitely getting more of them soon.
Top picture is a basic port with a cargo ship and navy destroyer. On the port itself is a building with a helipad and an administrative facility.
Bottom left is a spaceport with a small ship.
Bottom right is a launch site, and in this case, I used Brickarms M6 rockets to represent nuclear warheads.
