Face shape - Always start with a round base. Do not immediately drop to the snout, it looks unnatural. There should be a slight curve down for the snout. If you do the sudden drop, the wolf will look boxy.
Long snout - The snout should be pretty long. Canines have long snouts; felines do not.
Eyes - Your eye was two human-like. make it more animal like - either rounder or slimmer, and bigger.
Ears - Ears should be a rounded triangle.
