Haven't done a refline in a while, heheh.
Anyways, I hope this helps. CONSTRUCTIVE CRITICISM TIME!
Wolves have a larger, rounder nose. Small triangles would be found on a cat's muzzle.
Wolf legs are thin but not scrawny.
Their tails do not go up. They're not all that long, and are kind of bushy in one small place.
Most of a wolf's fluff is on the chest, I would probably refrain from drawing so much fluff lest it looks manged.
Wolves do not have a super thin snout.
