I think it was worth the risk of repainting the sky. I exaggerated the perspective by bowing rows down in the middle, and the big clouds are bigger and lower with less little distant clouds.
The outline shows the placement of the old clouds, which was too evenly spaced, and the rows were straight across. I’m trying to learn to orchestrate the sky, which can get a bit messy. After this, if I’m unsure I will be more at ease to rework my paintings.
