Nice drawing, I like the style, you have good potential as an artist.

The head could use a bit of work, btu the body is great. :3
One thing I must point out, though. Wolves are not killed in the way that your picture depicts, although there are many ways. I've noticed a lot around this site that it makes hunter's look "evil" or "money hungry fools". In many role-plays I've seen, people make the hunters kill half the pack off and come back two days later for more. What I just mentioned right there is unrealistic.
An estimated 15% of Canada and Alaska's wolf population of 6,000-7,000 is harvested annually.
That's not a whole lot.

(Don't get me wrong, I think wolves are one of the most beautiful creature's created by God. I love them.) But, I can see where many of you are coming from. Oftentimes wolves are killed off for preying on farmers' livestock, such as sheep and cattle, this enrages many farmers. You can't blame them, but you can't blame the wolves either. These days there have been advancements that benefit both wolves and farmers, loud amplifier-like machines that play sounds of wolves howling. This could lead the other pack(s) near the livestock to believe a rival pack has reached the livestock first. I can't say I'm fond of
all technology, but that right there is a great invention. :3
Anywho, enough of my explaining. Once again, nicely drawn picture, and I'm glad so many people have the hearts to take the deaths of wolves into consideration. <3
