This one is done. I've been calling it “Fifty Shades of Gray-Green”, but more than anything else it's a shape study with a little work on depth. 12×16 acrylic, graphite, and pastel on canvas.
Here's a canvas I painted for a friend. It took me much of the last half of last year, but I wasn't in a real hurry. Sunset colors were the only instructions. She loves the beach, though, and I promised her a castle. This is what came of that.
