The storm came trough leaving inches or rain behind. Here's the same shot right after but by the next day it was all soaked up. It's the beauty of swampland, regulating flow in the watershed. A sponge that prevents runoff and flooding.
Here's my ground lapis applied with egg tempera. I couldn't resist a bit of a royal touch with W&N gold gouache. Something like twenty layers at its darkest. It's a tiny swatch, only about an inch high.
