That's pretty awesome, VERY in depth. A couple things don't make sense to me, like that it starts snowing before the trees loose their leaves... And branches. Or that the sunlight is more slanted in summer than it autumn, and that trees bud before their leaves take place, but it's just a couple little things like that. Well, the times when the trees loose their leaves is kinda a big head scratch to me, because when Im from the leave fall during... Fall, but if that's the way you want it, go for it!
Are the seasons a big aspect of path of revelation, or is this all just to have super nice ambience?
