It is a good 1v1 to 3v3 map.
The hill in the center gives some nice tactical options.

If you'd use the original metal patches then the two corners are not entirely balanced. But that is easily fixed.

Oh, and it seems Klon accidentally named a map Cold_snap too.

I think metal spots are pretty strong in center. Possibly too much so, should be more evened out a little. It could be fun to play with that middle mountain, makes things really interesting, which is always good, even though it might cause some rage due to extreme altitude quirks (camera- and unit placement wise).
