First of all, it's difficult to tell looking through fifty-year-old eyes at a photograph displayed on a fifty-month-old laptop, but this photograph looks perfectly exposed to me. As far as I can see, there are details in both the highlights and the shadows.
Secondly, the fox's eyes appear to be razor sharp, so you have focussed on main subject. Your choice of lens, aperture and distance from the main subject has produced sufficient depth of field to render the rest of the fox sharply in focus, whereas the background is reduced to a blur. This draws the viewer's attention to the main subject.
Finally, I like the diagonal composition of the photograph. But, if I were to criticize, I would say that there is a little too much empty space on the right-hand-side of the photograph. I think the composition would be more balanced if a little of the right-hand-side of the photograph were cropped. However, that said, top of my wish list is to have seen Basil's brush!
