Hopefully, there will soon be more books on the market by artist, Ray Hendershot. I have probably 50 books on watercolor techniques. His book TEXTURE TECHNIQUES FOR WINNING WATERCOLORS is, by far, the best I've seen. It has carried my painting to a whole new dimension . . . especially in landscapes. If you like a subdued palette, such as that used by Andrew Wyeth, you'll love this book. It is an excellent tool for advanced beginners and beyond. The watercolors I've done after practicing his techniques constitute my best work to date.
