Winter is coming, even as autumn continues to provide color, fog gives way to snow, a waterfall, and trees. This is definitely another image that benefits from being seen big, the scale of the waterfall and trees are hard to take in in a web thumbnail.
The trickiest big in post processing was a hot spot on one of the cliffs on the left, it still needs a tiny bit of additional tweaking, but I've worked to preserve the feel of the real light without having a less interesting part of the image take on an undue importance. Details matter.
