Sorry about the wait for your critique, this is coming out of the backlog!
A very capturing image. I'm a big fan of fog and you did a great job of showing it. I gave this a 7 during voting so I feel that you should have scored better, but a 5.7292 is still great! The person in the distance is a perfect addition to this photo. As someone else mentioned the only thing really needed to be added to this picture is some more contrast. I'm unsure how I feel about the white at the top right but I think it fits in so I wouldn't change it.
Back for a second look and I like it more now than before. The subtle change in gradation allows you to layer the silhouettes. So you've added some depth to what would otherwise be a flat image. Nicely composed also.
Setting nice and the monotone works for this type of pic and the mood created by it. The big shadow tree does not look very sharp but im unsure if this really needs to be for this type shot. I would love to see a couple holding hands walking through this lovely scene. What Im saying is purely personal and for another person solitude would be there preference I presume. Only thing that Bothers me really is the white empty space at the top right. It takes me to much away from the core of this pic. This needs to be enclosed and protected for this mood to be carried stronger...But then we did not choose for these trees to grow the way they have :)
