The pants and cape are pretty good, although the chest/abdomen may need some more detail.
My first thought when I saw your image was that "Is that a wolf helmet?" needs more horn distinguishing.
Fingers on the left hand are a bit long too.
Horrid with hands, I didn't see a whole lot of need for chest-plate detail, I'll revisit it in another drawing, the helmet was designed to be smooth, but I see your point.
I'm no art critic, but his left arm is a little rigid and tight.
Left on his side or yours?
If it's on his side, he's holding a gun to some guy's head, of course it'd be tight.
If it's on your left, I didn't have another way to put it.
