To me, the image feels extremely flat...there's no sense of depth or distance between the objects and the background. Also, from the angles at which the wolf and Red are standing/moving, it doesn't really look like they're even supposed to be in the same scene together.



My suggestion would be to use more (deeper) shading on the trees in the background - as well as behind the rocks scattered in the foreground - to help create the illusion of depth; and maybe put Red a bit closer to the wolf (you could even paint it so they overlap a little) so it looks like they're actually interacting with each other.
