I love the movement and lightning effects of the bird. WONDERFUl job, there.
I would've liked to've seen more attention to the background in this, in that I think it could've REALLY upped your composition somehow.... I mean, the figures are GREAT, and the background could've helped emphasize their movement. But that's more thinkings for next time--just be aware of the impact a well-composed background can have.
That is absolutely gorgeous. There is so much movement and life in this picture. The detail is extraordinary, the shading is magnificent, and the background is superb. Fantastic. My only qualms with it are the bird's left wing looks a little crooked and it took me a bit to realize that the wolf's right forearm is facing away from the viewer. Otherwise, wonderful work. I love it.
