Two patches in each of the side expansions are 720 minerals, rest are 1500 (normal).

Oh I like this, it's plain and simple. Good job.
The only problem I have are the main naturals, it's too open and far apart.

the nats chokes are a little wide, a disadvantage for terran earlier on. However, I believe the "double" expansions balance out that problem with tanks being able to hit with seige well over the minerals.

The naturals being far apart will have disadvantage for everyone...everyone can run-by through the naturals and it'll be too hard to defend.
I would suggest making it closer to the ramp or making the pathway smaller.

If it's a disadvantage for everyone..... then it's not a disadvantage at all. Not all maps have to be "standard" or typical.

Well if it's 'not' a disadvantage, then why did you say it's disadvantage for terran?

Read after the "however"

you can just pylon hop over the minerals, should fix that.

LOL map

Yeah, sorry, my brain is dead, all the work I had to do...
But yeah in a sense Terran gets favored and that's why we need to make the nats closer.

Update: Moved nats closer to main choke, and narrowed them somewhat.
