Here are some of my thoughts and suggestions:
- You have nearly three easily defendable expansions, all three with gas.
- Maybe you can have it so that the expo right behind the main can be accessed by land. Im thinking a route through the middle side expo.
- Expos on the middles sides: take out gas?
- How about ramps leading up to those outposts?
- The two are really close to each other.
- Maybe widen up the middle and push back some of the jutting outposts? Right now, all the action thatll take place is on that inverted-S.
ADDITION:
Proxy - such as proxy rax or proxy gate - is when your opponent builds his fighting unit structures really close to your base. That means instead of traditionally building in his base, he'll put his gateways or his barracks right outside your entrance, and sometimes inside your base for faster attack.
ADDITION:
Also, the first thing I noticed when looking at the minimap was how straight the terrain was. Im not a fan of that, and you dont see a lot of maps like that, since theyre usually not that pleasing to the eye. It works on some maps, such as Blade Storm, but only because it has that certain flair and theme to it.
