This is a very sad, poem, though a wolf is not symbolic of sadness, only his prey is. So one wonders, why is wolf here portraying an antithesis of his character. A wolf's eyes are never blue, they are red, green, blue and devilish to stare in to.
There is power in poetry that projects an antithesis, so I will have to bow my head here, as I failed to understand the deeper meanings. A 5/5 for the composition, the portrayal of emotions and the near perfect flow.
