I like rocks too, but rarely paint them. I like the abstract feel and the play with cool and warm colors.
I have had an obsession with painting rocks lately, and am lucky to live fairly close to the Gettysburg National Park where there are amazing rock outcroppings everywhere. This is a wonderful painting, full of light and color. I love it!
Your rock wall painting caught my eye on the 30 in 30 challenge--I love your use of light/shadow and warm/cool colors!
