Judging from the given screenshots, the terrain looked nice, but upon opening the map it was pure chaos.
The abuse of blizzard cliffs, the emptiness, the lack of trees.
The creeps are also not suitable for a melee-map, the 'random' creeps aren't a good idea either.
The middle of the map is a complete disaster with a level 10 hero as a creep which drops campaign items, it could never get approved with such things.
The rest of the item drops looks like they haven't been given a lot of thought either (searing blade, Arcanite shield, Orb of Kil'jaeden and a lot more).
