well it's very plain, most of the map is unused. Also, there are too few expos for the map to be playable. The map is obviously imo t favouring, since t can lift a cc to the only other gas expo, whereas the other too races would have to waste valueable gas on getting drop to do so. There are 3 players, but 4 expos in the middle? Looks like red has two expos fairly close to him =/

I think though that the concept with 2 ramps per main, and the center island could work well, if it was better executed. More of the map needs used, and that would include adding more bases. I also suggest removing the "extra" expo in the middle.

Also, I think you should try and get the 3 mains closer in size/shape. But I'm not sure if it's a problem now, since they are all big.

hm, yeah but interesting concept

the problem here is, that terran players will have a hard time with expanding, i'd suggest to add expos at the chokes at all mains
also, you could add some other terrain, like temple walls, around the middle expos to create a wider variety of options for defending

with some work you could make a really interesting map out of this
