Awesome! Sounds so cool :-)
Can't wait to see him hacking through some zombies!
Its good that you took the blue out because I'm assuming there will be alot of snow?
Legs are much better. You could straighten the front shin a little to define it but it does give a good puffy fur-skin boot look as it is.
I like what you did with the back calf.
I think it would look better if back foot was firmly planted on the ground, at the moment it sort of looks like it is up on its toe but is a bit odd looking.
I went for flat foot also because of the weight of the shield.
Here's another edit I did partly because he is fun to edit
I tried to emphasise the chest again but maybe its too much.
Also tried to make the hair highlights instead of just all bright - top of head doesn't look quite right on mine but just watch out for how your version looks against black or a dark background.
