I concur with others about the uniqueness of the map styling, and I find it particularity interesting how you've tackled the cities. The shape of the landmasses is also interesting, I'd like to see how it would fit into a larger world map.

Unfortunately the snow doesn't really grab me, it strikes me more as clouds...maybe try to make it look more fluffy and not have such a hard edge? I'd say the same thing for the desert texture as well. For the text I would say maybe try removing the stroke, right now it seems a bit blurred.

Overall I find this map and styling beautiful.
