I really like this map, it looks simple at first glance, yet upon further inspection it becomes clear that considerable effort was put into this map - the placement of doodads, terrain layout, balanced creeps and the overall theme work well to create a very pleasant Melee experience.
One minor issue I have, however, regards the Granite Golem's drop - the level 2 permanent item seems unnecessary. At a stage when players are able to take on a red camp that can also cast two storm bolts (golems, I mean), none of these level 2 items are going to have much impact on the game (apart from Boots of Speed, sometimes). I feel like replacing the permanent item drop with a level 2 book (or just fixed Tome of Experience) would make it much easier in terms of inventory management while actually having some minor impact on the game. But really, it's not a big problem.
In fact, there is one more issue I have, though it's only a visual problem - the cliffs throughout the map appear pretty bland in comparison to the otherwise neatly designed battlefield. This is especially noticable near the shops and red camps. Putting a few trees or bushes would do the trick, I think.
I noticed something interesting when looking at the shop area. The space between the cliffs made it seem like it'd be possible to sneak through if you cut the trees, allowing for shopping without killing the creeps or having Windwalk. It's actually not the case as the space is too small for even a peon to fit through XD However, in my opinion, altering that area a bit and thus allowing for such shenanigans would add some flavour to the map, making it have something distinctive and innovative. You could even use the Northrend trees in order to show what to cut so as to give players a small hint! It's just a mere suggestion, though, and definitely not something super-important. I just think it'd look very cool.
In spite of me writing essays about the smallest of issues, I genuinely think this is a very good map! I especially liked those solitary burnt-down buildings, they really convey the theme of the map and give this very feeling of paucity.
Cheers.
