This is redline for wenn.
You definitely show a lot of potential with your work, getting the base structure pretty well, but there are still some errors that I can see.
The head and snout appear a little too small. As for the ears, your wolf is very alert looking with his head up like that, so his ears should be facing forward. The easiest way to tell where to place the ears is to follow the jaw line. Like--
http://browse.deviantart.com/?q=wolf&or ... 44#/dq87ll -- if you look at the wolf in this reference, you can see this sort of ridge of fur that follows along the back of the jaw, and outlines the ears from the head.
Also, the eye should be smaller and closer to the nose.
For the back, wolves have a very slight slope, so it won't cave in like a horse-- http://wolfdog.ws/assets/images/autogen/a_Skeleton.jpg -- but they have a lot of fur on their rump, so it APPEARS that they do not have a back slope so much-- http://lupinicious.deviantart.com/art/G ... ious&qo=24
For the legs, the joints on your wolf are a little too straight and chunky. Their hind knees are lower, and their legs are much slimmer. -- http://sikaris.deviantart.com/#/d349kow -- that is an AMAZING wolf ref for fullbody anatomy, even paws.
For paws, wolves do have very big paws, but they squish down quite a lot when they stand. All of the toes are also not the same size. Some toes-- the middle two-- will pop out more, while the other two fall back a bit.

Showing a nice bump around the shoulders/chest can really help to pronounce your wolf's anatomy. The shoulders don't blend down right into the legs in a smooth line; they slope back, before going down with the foreleg. Then there is a bump where the wolves' "wrist" is, and the rest of it is all paw. (see the skeleton).
The tail comes right off of the spine, and should be a little higher up, as well as maybe a little fluffier. Tails do tend to fall into the lines of personal preference, however. x)
Reference as much as possible, and never stop practicing!
It helps to keep a store of references to bring up while you are drawing. All of the references included here are stored up in my canine bookmark folder.
