Whoah, this one really caught my attention! <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)" /> Those poses are absolutely epic, there's so much obvious movement and struggle in them! So congrats on that, your fight scenes always absolutely amaze me. Probably because whenever I've tried to draw them, they never turn out that great. xD Anyways, to start, overall this is an excellent drawing.

So I'm going to start off with anatomy and then go onto some other things, which is what I always do when I do crits for whatever reason. P: Easiest for me, I guess.

Overall, there's very few mistakes, and most of the ones that I do see are more like, here's a way that it /might/ look better with, but not necessarily, because this is pretty good in terms of anatomy. <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)" />

So to start, the leg on the black wolf. They look really great overall, you can see that he's really pushing to get that other guy over. <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)" /> But I think that turning the back paw that's closest to the camera inwards a bit might look better, but this is one of those things I'm not entirely sure about. xD

Moving on, the leg (also the back one closest to the camera) on the grey one just generally looks a bit...off. I don't entirely know how though, it kinda...does.

I'm also a bit unsure about his front paw closest to the camera. The part between the paw and the shoulder doesn't look quite right...almost like it's too thick or something.

The grey one's head also looks a bit small, but that could just be because of all of his crazy floof. X3

I'm not going to make any crits on the floof on the necks, or on the tails, because I feel that the way they are drawn is part of your style. :3

Anyways, moving on.

Your colourings looks fine, no probles with that. The hard colouring and shading makes the scene look really intense. <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)" />

The general composition is also excellent. The wolves are nicely centered, and the way the lightning points towards them really brings out the faces. <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)" /> Well-done!

The rain, however, seems a bit wild. Though I doubt that all rain falls at the exact same angle, your rain seems a bit crazy. I'd recommend having it at least fall in the same general angle, as some of them seem to be going in completely different directions. xD

And that's about it, really. <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)" /> Overall a very nice piece, but there are still a few things you could fix up. X3 Great job, and I hope this helps!
