Will you have those eyes in focus!! That is hard to get with a moving subject.
Pity the legs have been cropped off. When I do something like that I usually look for a tighter crop to cover the mistake.
I would suggest cropping much closer to the "subject" >>eye and prey. Not sure if I'm allowed to post editing ideas.
In Australia foxes are a big (introduced) pest and have killed off much of the small native wildlife >: ( Best shot with a gun IMO.
