That is quite a composition ! And very rarely seen here :)
Anyway, really warm use of colors, but the perspective / proportions are sometimes weird (like the reindeer being as
tall as the tree), but i don't think that matters here. I think i can see some kind of dragon on the left part of
the mountain, that's funny (though maybe it's not a dragon ^_^').
I like the opposition between the sunset / brightly colored autumn trees and the darkness creeping in from the left side
of the drawing (plus that part looks kinda burnt down or something).
Really nice job, thumbs up and fav ;)
