Here is a picture of an experiement using paper clay and modeling paste to do a bas relief type sculpt onto a wood panel. I really liked this technique but, it is labor intensive. I used Golden brand acrylics and a little pearlex powder to create the color. You can't really see the pearlex that well here. Oh, and I used some of the duocolor acrylic paints from Daniel Smith. Love those colors a lot. This is called Sun On Blue.
