Here's the map that I used for a melee contest on warboards (February contest, I think). Two player jungle map. Hope you like.

Don't mind the Xel'Naga temples in the picture... I took them out.

Eh, i dont like the natural setup on low ground like that. I feel it would make for awkward gameplay during those first 6-12 minutes. I'm not sure how it would unbalance things though.

If zerg 3 hatched they could block both the main and natural securing 2 gasses while protoss and terran can expand but will have trouble defending from the lowground position. Thats a concern for me. Not bad though, maybe switch the gas from the second expo to the other mineral only.

It's a decent map.

This somehow reminds me of Blue Storm. Lose in middle, lose the nat, thus lose the game.
