I want to start off by saying that all of your pieces are phenomenal. I love where you chose the focal point (the wolf's eye's meeting the tail) to be. It draws your eye there before you take notice to the background. The lighting is also coming from the direction that has more space before it hits the focal point, making a bigger impact. I love how in this picture, the background wasn't as blurred, but it was all shaded, making the white wolf stand out beautifully.
On a less serious note, I love the unique position of the wolf The legs are in a funny place. The face on the wolf is absolutely adorable.
