where can do Z f.e. if spons are 2-10 or 5-7?

It is one older map...
But I'll remake it. :)

Well looks like a hard map to me. But that is cool, i like such maps. But if the map is so hard you can at least make all locations without a drop zone for terran tanks. At least that...

Edited.
Divided middle elevation, changed expansion/base area, entrance heads to border of map (before to center) and some smaller changes.

This map looks inpossible to me. If you make so little space for building that means that you force the player to get down and don't use his high ground - OK. But how i will go down and defend so big entrance? At least you can try to test it with terran wall, is it good wall on every location. Protoss may start on the high ground. He don't need that much space in the begining. Zerg is np i guess.

Anyway tha map looks very hard for players, they are force to do many things, and things that they might not want it to it.

And btw look at the room for player at 11 o'clock and player at 5 o'clock, and 7 o'clock too... And do i have to say that with such hard start for everyone, and a hard map you've made the main bases easy to get by sige tanks?

Resized bases.

I think you can use on this map many strategies, there is quite easy to drop to minerals (I hope it counters siege tanks on cliff - it can do every race) or lurkers under cliff by minerals (and overlord to see the workers upstairs) or storming workers from rocky ground...

About space for terran, buildings on expansion can be covered by siegetanks from main, I guess.

I think that if you want to make a real resize of the main bases, so they have many space for build and drop, you should use the water behind each main base. Just make the water a part of the main base, and it's done! You got space to do whatever you want. Good luck.

LGI is right. Move the starting locations "back" while you do so, it sucks when most of your production is "behind" the minerals.

Edited bases.
