I hope this helps! A few tips:

Make sure the legs have bones and muscles. You can look at anatomy tutorials for these.
The neck should be a bit shorter.
Ears should be a bit smaller and softly rounded.
Wolves have a lot of fur, don't be afraid to over-do it.
Head should be more defined.
Try drawing the wolf, then adding the fur. They're skinny underneath all that fur!
Looking at refs and practicing is the best thing to do.
