I whipped this up pretty fast. There's two versions of the walk, the first one being more of a "direct" walk away, like "I'm leaving and I don't give a crap" and the other more to what you originally had. Overall I'm confused about the wolf's emotions, you say you want him to be arrogant and do badly towards the other animals (and I assume he'll learn a valuable lesson), but you draw him to look so nice and gentle, which is also becoming bit confusing. If you want him to look/be arrogant, it's okay to give him a bit meaner expression, especially is you want this to be clear for kids, etc. Because right now it doesn't look like the fox is sad because the wolf wronged him, but be sad because the wolf is leaving.
Would it be possible to get an Overpaint on specifically the wolf anatomy? I am fairly confused with him I must admit.
