I like this shot overall, but I'm going to start with what I don't like about it.
Negatives: The backgrounds blur is quite distracting from the beauty and warmth of the picture and takes of the main focus away from the wolf and into the trees which isn't what I would be aiming for.
Positves: The warmth of the colours is fantastic along with the pale, cold colours of the wolf's fur, and the angle is very nice. I love how the grass is green nearer the camera but as it nears the wolf it becomes a sort of golden orange. You'll notice I gave you 5 stars for originallity. That is because there is very rarely and shot of a wolf howling in what looks like a free enviorment with the full body in the shot.
I love how you caputred the tranquillity of sunset yet also gave the feel of strength coming from the wolf.
