He is handsome! Nice shot. Were you using a flash? There are wonderful catchlights in his eyes. On my monitor, the image looks as if it could use a bit more contrast?
Not sure about your uploader and sizing. I would also like to admire your fox image larger. Is that possible?
I am sure others more experienced than me will offer better advice.
Better? An indulgence, yes, and I thank you. These old eyes can now admire your fox.
I love his coat detail and that the background is blurred enough to allow the fox to shine.
If I may be so bold, I have made an edit to your image. This is just my humble opinion, as I certainly not a techical person. My edit is not better, just different.
Here is a thought for you. Most people I know usually read from left to right, so what would happen if you positioned the fox from left to right? I also applied a vignette and provided more contrast.
