This piece is stunning, to say the least. The use of shade and light has been exquisitely used, be it intentional or not, it has worked very well. Your camera has pinned down every inch of detail, from that cheeky little tongue to the fiery pelt of this bold-looking fox.
This piece is really a delight for the eyes and imagination alike. The white around the muzzle gives our furry friend some innocence while still looking intentionally cheeky. The rims of black around the canine's ears stand boldly and proud, as do the furry whitish insides of the ears. The one shaded eye and other vibrant also give a sense of mystery to this little chap/lass.
Well done, you have done some amazing work to achieve such a quality of focus. Amazing, simply spectacular!
