Here is the larger work, 19 x 14.5 inches, titled "Rain Dance" because when I took the reference photo a few years ago, there was a light pattern of rain on the water. Maybe you can see my indication of it in the darkest water area on the left side if you click on the image to enlarge it. The hardest part was the bright, pale lichen. I took clues from the little study I did. It needed to be light and airy as in the little study but more detailed for this larger work. I think I did it.
