[sub]Heres the whole picture, im not sure how you always get your maps corrupted.
Its too open, you need a choke at the main otherwise toss cannot defend agaist lings, because lings can easily run around zlots. Also, the rest of the map is very open and boring. The expansions seem randomly placed. Blues mineral line is set up so that red has an advantage ( See how one of blues minerals in behind, making it ahrder to mine? )
Another thing is, the middle how it is now really favors terran, they can place tanks there and easily secure half the map, and when you give terran 4 free expos, it starts getting out of hand.
My suggestions, is open up the middle, make it a bit bigger and maybe use some extended bridges to make it more open. Also, expand the rivers down to the mains, and make a choke. Remove the high terrian behind blues base or add the same thing to red. Also, decorate better and put more varity into the map. Random streets and dirt is not very appealing.[/sub]
