Please improve the map description. For melee maps, put a short description about the lore behind the map in general, and list the number of creep camps (green, orange, red) and identify the neutral buildings if they are Goblin Merchants, Marketplaces, etc. and where would the players find them. In the same manner, list the number of gold mines (starting and expansion) along with their respective number of gold.
It says it's in Alpha phase, so would that mean that the map isn't completed? It should be at least in a playable state or mostly complete otherwise you should have to finish it first or put it in Map Development in the forums.
Screenshots (Map overview, terrain, gameplay) are appreciated and would better sell your map than just the default minimap and short description currently available. Best luck to you and hope this gets approved!
