Great shot. I think it’s your best fox shot yet… and that’s saying a lot. I have no problems with the wooded background. If this were mine, I’d be thinking about what wall I’m gonna hang it on.
Gorgeous light, pose and setting! Something isn’t technically perfect with the capture/processing, though. Handheld? Issues with NR or sharpening? It’s a lovely image, and the raw file is worth having another look at. Were you maybe in burst mode and got a slightly sharper one?
