my original inspiration as far as the snout on my drawing was the werewolves from Dragon age origins. instead my snout i guess ended up looking like a horses but i suppose that makes him original as far as werewolves.
with respect, I think the head still reads as "horse" because of the comparatively wide muzzle, short mouth, narrow cranium, and dorsal mane.
If you do a google images search for "wolf", you will see that the muzzle is narrow, and the head has a sort of ruff of hair towards the junction of head and neck which makes the edge of the face appear broad and almost circular.
The problem with the "horse" look, I'd suggest, is that it implies herbivore rather than carnivore - which is, I guess, OK if you want a vegetarian werewolf
If you'd like, I've done a rough alteration in photoshop, to show you the sort of changes I'm suggesting, but I'll only post it here if I have your permission to do so.
The other thing I note from doing a google search is that when snarling in a threat display, wolves tend to adopt a posture with the ears flattened (which you'll note the dragon age ones pick up on).
