This is my favorite sky so far. I was inspired by @david.grossmann.artist who you should definitely go check out. These so very talented young people! Jeez!
I don’t know if you can see it or not from the photo but the sky is made up of a bunch of tiny brush marks – differing colors but the same in value for the most part. They all kind of melt into each other and I love the effect. I have to try it now in a sky with clouds.
