You took this a lot farther than most of us expected (
), but you can take it even further. For one humble suggestion, he should probably be hunched over more, like this:
This means a stronger line of action, and a more dynamic, werewolf-like pose. You can have the werewolf standing straight up but the back muscles/hunch should be somehow evident. Few other points:
Parts of the limbs seem a bit straight angled and tube-like at the moment, hopefully that will be avoided in the final version.
Rimlights around thicker fur would be brighter/larger than areas with thin fur, this is abstracted around the head and left shoulder. You can find some refs of that situation online as well.
The rotation of the head looked a bit odd, the snout should be lengthened and the fangs should be larger if you're going for a straight-up wolf face. Amalgamations between wolf/human exist as well (American Werewolf in London comes to mind).
More than a few liberties were taken so I will be going in-depth on things soon (I.E. texturing, lighting, background detailing), sorry if it was brief.
