I like absolutely everything about this shot...From colors to detail to narrow DOF , exposure...You name it you have got it picture perfect...ANd the wide angle just gives it a totally different look you dont normally see with a wildlife shot ..Normally they are all long lens with heavily compressed FOV....this is totally opposite and even though you have used what appears to be a relatively narrow DOF the shot has almost a 3 dimensional feel to it...Especially with the depth of the shot!.
You have now got me fired up to get my 16-35 out and try it out with wildlife which is the last thing I would have though tit any good for !! ....Although Im not sure how Im going to get as close as you got to this fox... That im sure would have been a feat in itself ... ...But its paid off in a really big way to get such a great different syle of wildlife shot ...Well done
