The map overall looks good to me. The mountains look a little funny though, like they all end in cliffs facing the north. I think the black shading in that direction is too bold or short. One lake (NW continent) has a bunch of green artifacts (or really small islands) in it, and I'd clean it up. A large portion of the coast is a bit grainy around that area. The rivers in the greener areas are barely discernible even at full view with my screen brightness and contrast all the way up.

Other than that, I think it looks great.
