I'm really sorry I missed Paint Louis a week and a half ago. I check the What's Happening lists frequently and didn't see any mention of it. Maybe the organizers didn't want a crowd of gawkers getting in the way of the artists.
This panel on the flood wall attracted me. It took a lot of planning and precise execution. The sun and the earth, I suppose, although I don't know how the spiral fits in. And the scene has my favorite kind of light, bright sun coming from behind the shooter and dark cloud in the background.
