1) Watermark is super distracting here
2) For some reason it looks more like condensation on the lens to me than fog, or something. But even if it were, it would still be pretty cool.It just feels like it would be more satisfying with some visible fog bank edges or something. As is the top is a tad muddy and indistinct. Not necessarily anything technically you could do about that in the moment.
3) There's some pretty significant posterization in the sky. Looks like it was initially heavily over exposed maybe? Did you start with a RAW?
Overall quite nice, though. Good shapes, pleasing colors and (final, at least) exposure
