You have a very sharp focus on the fox, and a shallow focus as well so the fox will really stand out. Too bad about the foreground branch, but some things are out of our control. I have very mixed feelings about the desaturation of the background (and foreground). In my personal view, having the subject in color with the rest of the image in B&W is too much of a gimmick, and its history of digital processing stands out like a sore thumb. Also, because you did only "partial" desaturation, we're now left with spots of color here and there, and I find that to be quite distracting, to the point that I'd say to go all the way if you're going to desaturate the area surrounding the subject. Still, it's hard for me to imagine a background that I'd want to "reduce" by taking away its color, especially with a shallow DOF, but I need to emphasize that's my personal bias.
