Well honestly this map isn't something special!
I like how you placed tiles on ground and placed some doodads like shrubs near rocks etc etc!
But I also don't like how you created whole template...
Just nice tiles some blizzard cliffs and large number of trees!
No road or some path on ground! Use pathing blockers to create nice cliffs etc etc!
Few neutral units placed on ground are good but you still miss birds etc etc!
Well and this above was let say some basic stuff!
Now come let say advanced
I don't see any special effect doodad!
I don't see any figure created with some doodads! [simple example will be ice bridge created with few ice floe doodads]
No invisible platform doodads to create some awesome effect! [awesome stuff when you need custom created bridge, or some epic stuff in cinematic]
I don't see any lightning effect doodad!
No global effects, no light, no fog, no custom sky!
...
I don't know how to rate this so I will not

But I want to attach few tutorials uploaded here on THW:
