Nothing wrong with that picture. Love the heavy snow on the branches. The patch in the middle could be brown leaves still on the tree which haven't got snow on them. My guess is it was cloudy or part of the scene was in shadow, which results in the path been brighter than the rest. A slight tweak in curves would bring the best out of the picture.
You should never delete a picture that you don't like until a few weeks have past. The reason I say this is because on occasions I have taken a picture and on first checking on the PC It wasn't what I wanted to capture, so was tempted to delete due to disappointment. Instead I left it for a month or so, then went back and look at it again and relized it was a cracking shot, just not what I was trying to get at the time.
