The is a great adult coloring book for animal lovers. The images are pretty, varied, and lend themselves to colorful renditions. The Colorsoft Pencils work just great - ideal for shading. If you like them, you might want to purchase additional colors. (I also have had good luck with using watercolor pencils - a little water on a brush and you have great blending.) My main criteria for adult coloring images is that the drawings aren't "sketched" but that each item has complete boarders; this coloring book meets that specification.
