It's really difficult to get a misty, foggy scene like this approved - I've tried! When the Moderator zooms in 100-200% to inspect the image, it appears unfocused and noisy. You can try to improve this by brightening it up a bit, then reduce the Highlights, add some Contrast, then use the Dehaze slider in Lightroom aggressively. Also make the White Balance a bit less blue. See the modified image after a few tweaks in Lightroom. (although lightening it up reveals some artifacts in the sky that would be hard to eliminate...)
I may be going out on a limb here but atmospheric fog is ruinous to Stock photography because it causes light particles to scatter in very unpredictable ways. Unfortunately, no amount of post-editing can fully correct for this random light scatter.
The dreamy, foggy landscapes you see in most professional photos are artificially added to a perfect daytime image in post. The desired fog effects are applied discretely to select image areas on layers giving the photographer total control of the effect.
Best advice, don't do photography in atmospheric fog unless it's purely for posterity sake (vacation or keepsake photos).
