Hi Giova, fog generally sets a nice mood for an image.
A few things..in this case the fog is a bit overpowering and is hiding a great deal of the image. I would like to see more of the areas of interest.
The main tree appears to be almost centered in the image and I would have preferred it offset.
An idea would of been to isolate one of the interesting trees and make that a dominant center of interest.(possibly the one on the right since it's not merging with another tree)
Finally I feel there is far too much space from the trees to the top of the frame and i would crop from a third to half off....
Hi Giova,
Agree with Dave's assesment. You may want to try adding a bit of contrast......to see if that pops some detail into the fog (not too much though or you will overpower it)......and I also agree with the crop recommendation.
