Beautiful! But maybe slightly too HDR-ish looking for my tastes in the processing.
A little more contrast and slightly darker might make it look more natural would help IMO.
But even as-is it's a lovely image, processing tastes aside.
To be honest, this photo was so difficult to process I've been putting it off for 3 years. The combination of extreme resolution (200MP or so) and difficult colour balance made it hard to work with.
Increasing the contrast just seems to make it look garish and oversharpened. If anything,
decreasing the contrast, while reducing the brightness slightly, seems to improve things. But I'm just as inclined to increase the brightness - the light grey rocks made the scene fairly bright, even though it was in shadow and only lit indirectly.
And that's just the luminosity side of things. On the colour side, selecting the right white balance, and I'm still not sure I've got it right - maybe it needs to be a bit more yellow and less blue. Saturation-wise, there was the heavily-saturated clouds against the desaturated foreground and shadows - I had to selectively desaturate the clouds, but am not sure if it was not enough, or too much.
