Looks to be oversharpened but that could be a trick of the tree bark and lighting. Overall it's kinda boring though. No real place for your eye to land...

Leading lines or curves generally have two purposes. One is to lead the viewer into the scene. The other is to lead you toward the main subject. It is most effective if they come in from the lower left because that is the natural direction humans visually scan a picture so easiest to pick up.
Trees make great leading lines but yours seems to lead the viewer back out of the image again. The trees themselves appear to be the main subject.
I think this image may look better in sepia. No clue why, just a thought. The vertical trees cut off at the top lead me out of the image. The slanted horizontal line does also. You really want people led THROUGH an image, or to a point that is the main focus of the image.
