working away

Trying to decide what color I want the "sky" to be.
My experience so far has been that I really prefer the tree paintings I've done with non-naturalistic sky colors. Yet I feel like they can't all be ochre.
Today I substiuted for a colleague's class, and she asked me to show them slides of my work. It was interesting to see some of these trees from a couple years ago. Some of them had sold pretty quickly, and so weren't hanging around here all that long.
