Fur
Black and matted. Littered throughout with scars and several large Golden scars run horizontally across his back.
Horns
Black curling Ram horns. Also kind of like the second set curving backwards.
Face/Mask
Not quite human, not quite wolf, but not really like any werewolf kind of hybrid... Pretty human, with canine teeth and ears, but still obviously has K9 features even in his human features. Wears a real wolf's pelt over his face for a mask. Not worn over the head like a headdress, but strapped around the face.
(FINALLY got the skull mask ^^) It will DEFINATELY be a wolf Skull over a wolf's facial pelt.
Face Ref #1
Most notable is the hole for his left eye. When the spirit that possesses him takes hold, black smoke pours thickly out of it.
Face Ref #2
Pretty human overall, but with abstractions and K9 features throughout.
Fangs
Goatee, braded w/ beads and hangs down below mask
Sanno's right eye. Yellow, often has tears flowing from it.
