I like your lineart on this...but I kind of agree with hideyourface. The shading on the dog is good because it implies the texture of the dog's fur. However, unless the human's skin is as textured as the dog's fur, I suggest that you fix the shading on the girl just a tad. But, the overall BG and pic is great!! Sorry for sounding like that....art teacher says stuff like that all the time to me because sometimes you see strokes when I shade. Just trying to help a fellow artist out.
