[sub]You're getting better, but this map is still meh. Gas issue firstly, a better choke would be nice. ( Right now you have to build at your nat to have any kind of choke. ) Remove the doodads from the middle, its narrow enough as it is. If you could open up the middle at all that would be good. The expansions above the mains are perfect places to land units and attack the main base, either whack it or try to get the main out of reach. Maybe add a mineral block in the expansions in the hole or the expansions above or both. Too easy for terran to expand early now, two very easy to get expansions.
The mineral formations are not very even, maybe go with symmetry with the minerals too. Oh btw, if you don't know about the gas issue, read this article by starparty.
Here. It's nothing major important, but it does make a difference in long games, in short though, its usally best to place gas nodes either directly above, or directly to the left of the of the main to gather gas the best.[/sub]
