This is very good, i enjoy the coloring choices. The orange of the leaves contrasts well with the black fur and the grey background. I was about to say that the muzzle was a bit too long, and was looking more like a fox, i had to look up a picture of an actual wolf for a minute, and sure enough that's what they look like, which also proves that you have a nice and decent grasp of canine anatomy. Overall this is a well done piece.
