The idea was to have two paintings with opposing colors one next to other. The first one had a girl getting lifted by a huge balloon and the second one of a boy offering a huge flower (the initial idea was that the boy should be getting lifted by the flower too). The two paintings were to be functioning complementary.
For my personal record I copied the blue one which I liked it more (in the other painting I was having trouble with the color of the balloon and the brown shades of the orange background). You can see a photo of the original set clicking the thumb here.
