I really like your head style~ you don't have to bother messing with it IMO
secondly, I use stylized anatomy so it's not 100% accurate, but...
Wolf legs are pretty much composed of the same parts as human arms and legs. So, for front legs, sketch in a shoulderblade, an 'upper arm' and an 'elbow' - the first and uppermost circle in the blue sketch. Blah blah blah, lower arm, then a wrist. In canines it can't really bend forward like you did in your original drawing, though.
I think a longer body was in order, and to stay balanced that right front leg would have to be placed in front of the left front leg. :3
Next, BACK LEGS!
I notice a lot of people have trouble with 'em when they first start drawing wolves - I know I did! They are also composed of the same parts of a human leg. The first and uppermost segment is our upper leg/thigh and it is generally the thickest part of a wolf's back leg. Then where it connects to the middle segment is our knee - and that middle segment is our lower leg/calf. -rambling-If I confused you - I probably did heh - then just ask a question and I'll try to clarify~
