A tad bit tight.
And it still makes my eyes wanna barf when i see it, you do need to work on decoration!!!

Suggestion: Make center field bigger, and remove those mins in mid they will play hell with the game.
Suggestion2: Main is too undefended, try cliffing the outer rim of it.
Suggestion3: Use the nat space (its too big imo) to make center bigger

Balance:
P < Z
P < T
T > Z
Very anti protoss imo.
Very pro terran too imo

My Choice would be: abandon the map, its very imba and layout is just ick.

If you want to make a nice melee map use SCMDraft2 it has mirrors and crap.

Um...looks to me like he has SCMDraft2 already judging by the symmetry.

I have to totally agree with you.Reason? Like deathman's opinion, protoss are very weak and terran too strong in this map, which makes the map very imbalanced.Try to baalance it more, or abandon it.
