1) You made a typo: The war betwen the Naga and humanety is still not finished,
- betwen --> between
- humanety --> humanity

2) Work some more on your terrain. And I mean ALOT. xD
- I saw tree's with snow, and the weather effect is also snow, yet the ground is made out of grass, and it seems gras only.
- It's lacking doodads alot.
- The cliffs are just to... well.. ugly? You don't realy use 'shapes'.

3) It seems you just randomly placed units on the map, some are not even having a good purpose.

4) Player Blue seems to have an advantage to all other players.

-Overal, the terrain sucks, sorry but it's true, open up some melee maps made by blizzard and try to use that in your terraining skills. You could also look for some tutorials.
Make the players equel, overpowering blue will make the map more unbalanced to me.
-Remove the random placed units or place them somewhere else to form better creep camps.
-Balance it out more, either test it with some friends or request people to test it for you.

Score: 1/5
It might be a good idea, but you need much more work to actualy make it a good map.
Good luck with improving your skills young one!
