Shih tzu and Tulips, oil on canvas, by Cathy Huff . Cathy has been a student of the Painted Palette for a few years now. She has painted landscapes, still lifes and has recently been working on a series of canine portraits. This one is one of my favorites. Cathy and I enjoyed the progress of this painting from beginning to end. It developed from a composite of photos. She tried a new approach to her canine portraits and painted a very successful portrait.
