Well I tried the map, and heres what I thought.
The music you added, in my opinion, doesnt fit the map type at all...
Its very slow to start, and theres really nothing that makes the map stand out.
Items, heroes, and the hired units are all from wc3. So its not very original.
But, You said your new to the editor, and all things considered its a decent map. Keep working on it. 3/5
