Leaves turning toward the end of Sonoma's summer. I eventually painted over this on another visit, updating it to a summer tree.
Added Note: After posting Rust Tree 2, I realized that they were in reverse order. I painted this one late in the afternoon. You can see it's become overcast, as we head into Fall, and there are relatively no shadows, and the sky appears almost white.
Another interesting thing happened. As the air temperature dropped, the paint refused to dry and it became more of an oil painting experience. Quite the opposite of painting on those hot breezy days of August when the paint dries as soon as it's applied.
