Is it missing ramps? It looks like there should be a ramp in the top right corner and an inverted one in the bottom left. The build of the map just looks like that is how it should be, but if it is intentional islands then I suppose it is okay. The middle is MASSIVE. About 50% of the map is just the openness of the center.

Looks like a microish island map to me... Might just as well turn out to favor bunkering, after the gas nat there is nothing important left in the middle...
