I am helping. I am suggesting that you seriously play melee for once in your life, and see your map then. You'll see why I told you, because you'll see a lot of things wrong, and you will know what to correct all by yourself.
I do in fact play melee, it just has been forever that I have ever used to be as good.
None.
It's because you didnt play it seriously. :\
None.
It seems very difficult for Z to set up a defense after FE to the nat, since it looks like units can go up the ramp straight toward the main without being bothered by the nat, so Z would have to have sunkens in both areas which damages the economy. Also, can the expansions behind the bases shoot into the main mineral lines? And make sure you remove those bridges.
None.
