See the update (the next post, above this).
The funny thing about doing art is that the whole world becomes source material. When I design and paint theatrical sets, I see items or color combinations that fit the design I'm working on. In doing these small paintings, I'm always looking for something to paint that's interesting. In this case, I saw these two bananas and it looked like two people spooning. Cute. So I set it up to emphasize that and painted it in complementary colors.
