I appreciate the feedback! Personally, I don't like to use textures in my work - I aim for a photorealism and I feel that textures take away from that.
If you could better explain "popping out from the background" that would be helpful. Part of the poppage could be the iris blur I applied to the forest image. I do need to fix a bit of shadowing on the forest floor from the wolf. Other than that, I have to respectfully disagree that they don't look like they belong in the overall image.
