A nice map and a cool (well, maybe cool is not the right word here) scenario as well. I always like seeing these alternate versions of familiar places, and as Thomas said, there is a certain strange satisfaction to seeing the Sword Coast in such a disarray. I also have to say, that the border in all its simplicity is almost my favorite thing about this map. The messy ink looks fantastic.

I noticed that river that Beee mentioned too, and honestly even with the explanation, it still just kind of looks out of place to me... Besides, the river flows from the lake to the ocean, not the other way around, yes? I'm not claiming River Police authority here, but that is a far as I understand this.
