I tried to put as many points on the picture as possible, the rest you'll just have to study.
I recommend putting the smoothing tool at 50%, and working on your perspective. I also suggest studying wolf anatomy on a regular basis; that's what helped me improve the most. Also practice on certain parts of the body only, like the paw, eye, ear, nose, etc. Using shapes to start out will help also, like I did here.
I hope I helped. ^_^
