Thick paint, scooped on like frosting! I’m having a lot of fun with this. It’s challenging, and less predictable. When I touch a spot with a brush it might spread out, blend, lift up, or reveal some color I forgot was underneath. Lots of scrapping areas off and trying again. Below are a couple more cloud studies, a small one I did from a photo and an afternoon plein air landscape (nearly the same spot as the one above).
