Overcast days is what we're having in the Texas Hill Country. A friend of mine enjoys them because they don't trigger her chronic migraines. They can be another kind of headache for painters.
This one was interpreted from Willow Creek. When the sun is shining compositions are driven by the contrasting shapes of light and shade. I have to admit, that's where my preference lies, however due to the prevailing cloudy days, I've been practicing interpreting those circumstances. For cloudy day paintings, we usually need to find shape contrasts in the local coloration of the elements in the scene. Not only is the compositional problem different, but the mood is usually quite different as well.
