I'm not quite sure as to why, but a lot of Animation Source users tend to think that "style comes first." Unfortunately, that's not true. (Trust me, I found out the hard way!) See those two pictures I referenced above? You can use those -- and more -- to learn
realism. I found those by going to Google Images and typing in "running wolf."
By referencing photographs for a short amount of time (or a long time, whatever your whim) you're
memorizing the anatomy in the picture. You're training yourself to know where this or that is, what size this is on the face, how this part of the body moves while doing this, and so forth.
Style should come last to anatomy! This is because, when worrying about style, you'll become distracted and your art will have a bunch of mistakes in it. And you and I both know that when there's a mistake, your eyes stay on that. It's like seeing a typo in a newspaper; it distracts you from the bigger picture.
Take some time, pull some photographs out (I've linked a couple of good on-line resources on the Internet; you can find more photos in books and magazines), and draw them. Take your time, try to make them look as much like your reference as possible. (Don't worry about detail!!)
Trust me, you're going to fail a lot before you produce one content piece of art. That's called "progress," but don't let it discourage you. Keep at it; endure the jerks who are going to bash your work and use them to make yourself better. (Who best to point out your weak points than an enemy?) By identifying your weakness(es), you can smoosh them. Do that. Need to work on drawing noses? Take a sketchbook page or two and draw noses at different angles. After you make a picture, find a reliable artist (me, Kaylink, silver Deni, Midnightwolf) and ask for critique. Or even post on the forums asking for it. Someone can help you by saying, "Here's you're strong points, but there are some weaknesses. This is what they are, and this is how to fix them." If they're really nice, they'll even give you some resources to help you along.
Frankly, it looks like you're trying to make your style similar to that from the movies.
Don't. Having a style that's copied from a movie is one thing; having one that lacks individuality is worse. Think of how many people have seen those movies. Now, think about how many people use the same or similar style to that in the movies. By working with realism, you can work
forward instead of
backward. You need to know what something looks like before you're able.
Sure, you know what an apple looks like. But do you know what a wolf looks like? It doesn't look like a husky, or a German shepherd, or the local mutt that roams the streets. Each animal -- even different breeds of wolves -- have different characteristics that make them identifiable. Learn those characteristics by studying photographs and drawing those.
Practice makes perfect -- but proper study makes for good practice. Too Long;Didn't Read (TL;DR):
Study realism, then work on your style.

stealing. Also, look around the websites and see if they do/don't allow using their photos as artistic references. Monty Sloan (wolfphotography.com and wolfpaper-archive) allows artists to use his photos, I have already contacted him on this.
