It's 2 small, look nice, but 2 small.
I suggest you to increase map size, add some more buildings and staff there. This way it can't be used in cinematic or minigame.
Also don't place 2 many units at same time, map is small so it's look ok, increase map size by 2 and if you place same number of units there as well WE will start to lag, same ingame... All big maps (RPG, ORPG and so on) use some kind of spawn systems to avoid that! You can make one as well after all this can be arena template or whatever...
Fix some minor problems and this can be approved for sure!
Oh another thing, small suggestion, place small fountain on top of big one, it will look better that way
Also you should put screenshots into description, mention how much doodads you used, same for destructibles, because some users don't use JNGP, so max doodad limit can be problem for them!
