StarCraft 2 Melee Map Contest

Sorry to say but this map needs quite a bit of improvement.
-For starters, there is one giant path that leads to both bases -- no secondary path. That kind of drops the options for gameplay.
-The expansions behind the rocks are too easy to defend, plus a terran player will have the advantage because the siege tanks can hit the path between the two bases. So this means ground attack really isn't an option if there is a terran player.
-I find it strange as to why you put a high yield and normal expo right beside each other
-There is absolutely no texturizing done
-the main bases are enormous

I hope these comments can help you build a great map in the future! :)
