It's always fun to do stray grasses and weeds. But now I see that I need to bring the fur down a little lower on the dogs to catch the weeds in the image. Also maybe I should open up that dark streak across the bottom with a patch of lighter snow.
I'm happy with the highlight on the black dog's back - it breaks up the large dark mass and shows more of the texture of the fur. But I'm a bit unhappy with the right dog's eye and feel that I still need more color in her fur.
