I really enjoy this photo, with the slight green cast and composition. I'm not seeing how it really fits into the theme (seems like the entire scene is the subject, which is inherently centered).
Excellent image but I fail to see a true subject that's off center, and the title points me to fog, which is everywhere. I'm not voting, just making observations. As a photo I give it a 9 for the tones and the mood and the clarity of what needs to be clear vs. the mystery of what's not; but I don't know how voters will place it in this challenge. This type of photo to me is more about what you barely see than the tree that's front and center. i hope that makes sense and isn't too critical. Again, not voting.
