Its an OK idea, I am sure there are many examples of high summer maps, with winter maps less common, but far more common than spring or autumn, so I can see the need for an Autumnal map.

Since I haven't officially started my Village of Nocturne map, which is intended to be an autumn setting, but with the twist of being a village map at night under the moonlight, but trees both leafy, coloring, and bare indicates early autumn, at least in the experimental sample provided in that link on the General Mapping WIP forum.

I could hold off doing the village, until such a challenge were to exist - if there's enough interest, otherwise I'm making the map on my own, as per my original plan.
