I thought of an outpost in a barren landscape with a warm, late evening atmosphere. As you can see the setting is in a dual sun system with two moons, which actually don't pick up much of the sun on the horizon - it looks better that way :) The air vehicles are on a routine patrol flying from outpost to outpost making sure everything is OK. I especially like the mood here. A sunset in a desert environment with a massive, giant structure in the middle of nowhere...
