Sorry for the late reply. The islands in the corners look quite nice. But the rest of the map doesn't really go with the ice theme, and I'm not sure why there are jungle trees there. Also, instead of birch and stone slabs in the middle, i'd say try doing some designs with snow and quartz, to try and keep with the snow theme. And I don' t really play skywars that much, but if what KasaiXenox says is true, that it's very similar to other maps, then maybe just scrap the idea completely and come up with something else.
Good luck.
