I love the designs in this coloring book. I've bought about half a dozen coloring books so far and I prefer those that combine natural, or "realistic," images with intricate designs. In other words, not completely abstract (like mandalas) but not just plain pictures of, say, a mountain scene or bed of flowers. This book is similar to another favorite of mine, Marty Noble's Art Nouveau Animal Designs, in its blending of intricate design with animal shapes, and it hits the sweet spot in terms of level of detail--it's not boring and it doesn't make me cross-eyed. I put "realistic" in quotes earlier because the insects in this book are highly decorated and not actually realistic at all. But they're fun to color. The only slightly negative comment I have is that some of the background designs are repurposed. There are a couple of beetles, for instance, set against a background that is also used in the Art Nouveau book (a picture with foxes, birds, and trees). I'm not super-excited to color almost the same picture twice. But I can see where it makes sense for the artist and/or publisher to decide to do this, given the low prices charged for these books. The paper quality is fine, and I like that the images are printed on one side only.
