I was inspired by some stormclouds the other day and painted a sketch of them. PB28 Cobalt and PO62 benzimidazolone orange. Mostly washed on as pure color + let the laws of physics do the magic. (I did mix a little on the palette for the very deep accents in the clouds. ) Added the lighthouse after it was dry, I just couldn’t stop seeing one there so had to do it. About 5″ x 7″ on a loose piece of 140lb paper, probably the Richeson stuff I don’t really like. Worked well here though!
