I don't know if the picture in the first post is the one everyone has been commenting on (it doesn't look like it... sand? Pyramids? Not seeing any...), but I just thought I'd ask if a snow map is what you're intending to do, since we already have Frostbite, and community maps Desolation and Glacier front?
If I was asked what kind of map I'd like to see (and I realise I'm not being asked, lol...) I'd say something like that level in MW4 Mercs where you're investigating the Jade Falcon presence on a planet..
Lush trees, lots of water inbetween the rising land masses, winding streams etc though it might end up looking like extremity with a marshes/clearcut skin on top of it.
