Vanity means not only conceit and excessive interest in appearance, but also (and more basically) emptiness, meaninglessness and futility--as in "our efforts and hopes were in vain." I tried to express the opposite of this week's prompt.
This is an image that has been rattling around in my head for awhile. I did most of it late, late last night when I couldn't sleep. I want to try it again, make it bigger and more complex, make the waves more watery, put some fruit, flowers or more birds in the tree.
Well, I just tried to upload to Illustration Friday, but I'm too late. The new prompt is already up--"revenge." I might have to do another opposite!
