Off the bat, I love the mood of the picture with the mist/fog really adding to that haunting and unknown atmosphere. The curve of the path makes a nice leading line into the horizon which fades nicely just out of view. The sepia toned colour treatment adds to the mystery by giving it and old feel like a place out of time.
The only small gripe would be the branches on either side as a slight distraction. Perhaps crop out the left end a little more and leave that main trunk as a framing line? Overall though I still think this picture is pretty good as it is
