I was told they look waaaaaaay better in person, but...
Acrylic, specialty paint, native red clay gathered from the depths of the backyard, on canvas.
There is a lot of copper, patina, metallics, and iridescence that was not picked up very well in the photographs. The two pieces catch light in many different areas when viewed from various angles. Each canvas is coated in several layers of polyurethane so that you can feel the different textures without damaging the paintings.
