This one has fire and ice. It also brings to mind Native American medicine wheels, because don’t those spikes that form the inner circle look like feathers?
I may turn this one into a greeting card on Zazzle. Since I managed to save them all at a high enough resolution, I can send any of them to Zazzle to create products. So if there’s one you particularly like, let me know what sort of Zazzle item you’d like to see it on.
