Quite a good map. Still I dont want to approve it yet, as there are some issues which could be fixed in a short amount of time however.
First some general notes:
-Despite the unusual tileset, the basics are solid.
-In many parts the map is rather linear (i.e. you can only go forward or backwards, but not sideways). Imho this can lead to static gameplay.
-Related to this: Large amount of unpathable terrain, for no real reason (from a gameplay perspective, but I can understand why that it emulates the true outland feeling).
-Interesting idea with the small wall of trees opening another path towards the main base. I'm normally not a fan of this, but I like how it is implemented here. But just on default exit to the main base can mean you can easily be trapped.
Now for the small, but imho important issues where the map could be improved without much work:
-At the orange spots, item generally are too strong in relation to the strength of the creepcamp. For example, a lvl 3 item shoud drop from creepcamps of lvl around 14-16. A lvl 20 spot normally drops a lvl 4/5 item and a lvl 2 powerup, whereas at the expansions on your map it is 5+3+2. Consider making some changes here.
-The natural expansions are guarded by very strong/annoying creep (mana burn + double cleave). This makes fastexpaning hard-to-impossible for hu, which could be a balance problem.
-The creeps at the shops might accidentially attack player units.
It would be great if you could adress these one or several of these 3 issues. Therefore I'll set the map to Awaiting update. If you say you dont want to make any further updates, please contact me and I might approve the map nevertheless.
