Old Axel Ref Sheet

Finally did a simple ref sheet for Axel.
So, three of his feet are dark, the fourth one farthest back is NOT colored. His tail is colored in an order of brown gray ending with the dark color and then with a lighter tip. His eyes are blue, and the insides of his ears are also dark.

Enjoy!

EDIT: It doesn't show it here, but he also has black eyebrows.

EDIT: Oh my god his back legs look so thin
