I LOVE it when this happens...finding an "incidental landscape" in another painting. Interesting to find another world in a piece you are working on.
I was painting a llama portrait for a breeder in Wisconsin, and turned the canvas sideways when I was moving things in my studio. I noticed this beautiful little place...reminded me of past trips out west and the color at sunset on the amazing rock formations.
I call this "The Canyons".
