You have a really nice concept of the base shape of the head, what I recommend is drawing a circle, then a trapezoidal shape for the muzzle. It will really help, you should try it ^^
One of the criticisms I do have is that the muzzle of the wolf is more pointed, but not a triangle. Again, this is where the trapezoid will come in handy. Your eye also seems to be more like that of a humans; with a few studies of wolf eyes in photographs from different perspectives, you can make small changes so that it overall appears more like a wolf's.
For the trapezoid and circle, I usually make the trapezoid about the same length as the diameter as the circle.
My last suggestion is to make the fur on the front of the neck come out a bit more, and combine that with the above idea, and it should work.
I hope this helped! Good luck, it's only small changes you need to make to improve.
