Yeah, this won't be approved. Mostly because it is poorly done and unplayable.
Being your first map is not a excuse to upload a poorly made one.
There are a lot of issues with this map. Lets name a few of them.
Being 3 players on a map this size could work if not for those narrow passages.
If you play as Night Elf you will not be able to entangle any goldmine besides the one you start with, because of those narrow passages in the corners.
The terrain looks unnatural and plain ugly.
I guess the tileset is nice (for a first atleast) but definatly room for improvement and I strongly suggest you use more doodads.
If you play with 4 players you will not be able to obtain any item drops.
Because the only permanent items are dropped by red mobs guarding the "starter" gold mines.
Some bigger units, are unable to walk to the enemy bases due to the narrow passages.
If you want to win this map simply pick undead and wait until you get Frost Wyrm's.
Strongly suggest you start over and try again, because unless you make major changes to this map - it is not going to be approved.
Also suggest you take a look at the terrain tutorials, because you got a lot to learn.
