Here are two somewhat heavy handed edits using the jpeg on .world. Obligatory I am not a great editor, but I think the fog needs a touch more definition and a more contrasting background to pop better.

The first photo has:

• local contrast to give the fog a little more definition. This is the only thing I masked, everything below was applied to the whole photo
• shadows and highlights, mostly to crush the treeline behind the fog some and give the fog more contrast
• tone curve + base curve, again to add some more contrast
• haze removal to make the tree line darker

The second edit only has the addition of low light vision to de saturate and further add some contrast.
