Before going into rigging I wanted to find the scale relationship between the two characters. Making them the same hight, somehow made the evil wolf seem less capable. However, he was already wider and longer than the good wolf. I believe the glowing aura could visually compensate the lack of good wolf's size. I found this scale least conflicting.
Also, and finally, I have the evil wolf's Uvs done. Took longer that expected. But then, he had ..10 times more of details than the previous one.
