Just a couple things (Oh boy!)...
Its head is too small for a wolf in comparison with the rest of its body. .... in fact I don't even know how to explain how to fix this, but it is.... let's see. What can I equate this to. Ugh... it's 3

0 in the morning. I really can't think. It's just too small. x_X Forgive me for not being able to back this up with how to fix it. =/
Secondly its forepaws are.... somewhat small. I think you can get away with leaving them like this, but wolves have notoriously large paws that act like snowshoes in winter. Not as big as lynx feet, but still bigger than the average dog paws.
Lastly................ I think this is both angle and the 3

0AM factor talking. >.> The way you have the wings.... attached to the body..... are passable. Aheh. Clear as mud. x_X Forgive me again. The wing muscles in birds have the same amount of joints as human arms: 3 main bendy ones. Wow. Real articulate Quel. x_X Anyway, from the shoulder part of the wing muscle, it goes into the bicep of the wing muscle, and then hits the elbow joint, which goes into the lower arm muscle, and down into the wrist and wing finger (or fingers, in the case of bats and dragons). You only have two here.
It's been of some debate on where the wing muscle actually connects to the body, but most seem to agree it attaches to the back and has a lot to do with the chest muscles, rather than the shoulderblades or behind the arms. Again, check out Ahkahna's work to see what the heck I'm talking about. Aheh.
Now for my actual POINT on those wings. Gawd. I'm lengthy when I'm tired. x_X The width is just about right, on how they'd attach to the body, and like I said, this could just be angle, but the primaries don't look like they extend far enough. Bird wings have wicked large primary feathers that extend at least one more width outward. One more width = the width of the wings from shoulder to ending point near the back leg there. They're REALLY big.
Arf. I gotta stop now. Ahehe. I think though, despite the fact that I can't frickin' stop talking, this is the best piccy I've seen you do. ^_^ Keep it up.

"HOLY FONT! *dies under the comment* You're trying to kill me ain'tcha? *laughs* Ohhh boy. You're right about the head... I just now noticed. (I tend not to notice much unless someone else points it out. Blehk.) Dernit. It's 3h30 AM? You're crazy! ^_^ But I appreciate yer comments nonetheless. *pokes Seleth's paws* Again... yer right. Do Canis have big paws? I can't remember. I think they do though. Dahh. As for the wing joints... I am NOT original when I do birdywings. I stared off a picture of a... what was it... bald eagle, I think... and copied the wings as exactly as I could. I'm lame, I know. *pokes da feathers* I think... I think yer half-right. I know the wings are angled, but the primaries could use another half-length, I bet, to make 'em look good. My only excuse... is... err... I ran out of paper. >,"
