WOAH! That is sweet. I like the craft also. Nice. How about adding a light cloud layer and keeping it low. That or just dupe the hell out of the ships. Wait. Idea. Lots of open space, which looks cool, but what about some towers coming symmetrically from the paths going out? That would add some busyness to it.

Because I like to blow $%&# up.

Don't fear the night.  Fear what hunts at night.
