The map's visual outlook is too monotone, the concept for adding neutral race to be a neutral creeps is conditionally acceptable yet was given a bad output you might want to given a creep camp positioning instead of a base of sort.
Also the way how the map is made is not too bright either, the proper location for both player parts must be diagonally placed to given the player/AI some quality time to make a move, also the population of enemy creeps is way too high and clustered with each other, it would be of better ease of you can calculate the proper housing of easy green camps to hard rock red ones.
I suggest you read one of our tutorials regarding melee map making or the better to play some of blizzard's melee/skirmish maps to give you an idea of what to do and don'ts of applying certain materials for the map. For now this is good practice, but not good upload.
