If you don't mind a little bit of a constructive crit, I'll throw in my penny. If you don't want any ConCrit, ignore the rest of my post.

Mainly, you need to make the end of the mussle thinner. The eyes need to come up more, making the separation between mussle and eyebrown clear. Don't make so much of a bump inwards on the bottom of the jaw, as the lower jaw is all one bone. it runs smoothly along. End of the jaw into the neck needs to be pulled back more. The neck joins the jaw before the jaw itself ends, not where it ends. Ears need to be set a bit more into the head. Canines(the larger teeth) are set a bit back further into the mouth than the front. Keep in mind that while the fur is long on the neck, around the eyes, nose, mouth, and other areas of the head/face3, the fur is extremely short, being more of a fuzz, while on the neck it is pretty much a mane, with long hairs.

Feel free to take a look in my gallery at the wolves done by my cousin, Reawolf, (not mine, please, mine are nearly as bad as yours! I can tell what's wrong, I just can't fix it... >> and she has some pretty good wolf linearts that I've colored. There are plenty of awsome wolf artists on DA, so take a look at some of their anatomies as well. All it takes is references and practice and you can get good pretty quickly. Just.. I'm too lazy to go get the references...

Anyways, there. Enjoy! Hope to see more art from you!

Why do we live only to die but we die to live?

thanks for the suggestions on how to make it better this was my first wolf in a while and the heads backwards so it was difficult for me to do. The person who wanted me to make this wanted it black and i havent done well with trying to do black and makeing highlights and shading with black. Though i hope to do better on my next.
