I started this about 4 months ago, and scraped it off, and tried, unsuccessfully again. Then it sat on the studio floor and every timeI looked at it I became more frustrated. Yesterday I went back into it. The "Canyon" is a challenge for me. Creating the 7-12 miles of distance, keeping sunlight in the distance, and then light in the shadows. I had to walk out of the studio several times and pull weeds in my backyard!
