Lovely work - for some reason, I think that particular fox has a GORGEOUS face, and the leg anatomy looks great. Gotta say, love all those little different tones in the fur - adds a lot of realism and makes it look more interesting ^^
The beauty and detail of this piece just takes my breath away. Your anatomy is excellent and the colors just look so nice together (the fox's red fur and the green background) keep up the great work my friend
