And that actually is the snow road autotiles, Irock; the ice autotiles are blue-ish in colour and smooth without details. I've been planning to use a different road autotile for that in the near future though, heheh.

I like the sense of elevation in that mountain map. :> I'd suggest adding some variety to the trees, or perhaps simply recolouring some of them to have a little variety as the elevation increases to signify altitude.
