Well, with respect to gameplay there isnt much to say, as everything is looks fine. Nice to see many unusual creeps. I dont notice any that I would call problematic.
The gates, while I dont like them in general, are also used in a sensible manner.
Regarding visually, I think the map loooks really good. In particular the central areas look nice, but the map does not feel overloaded with doodads. There are some doodads which I'm not sure if I've seen them before, such as the "skull torches" or the ice spider statue.
However, I doubt the tileset will find the approval of the majority of players.
Map Approved.
