Pat's Radishes

I paint with a group at Pine Island Art League on Thursday mornings. One member brought freshly picked radishes for a still life painting. They were so interesting (one was huge) with their bright green leaves, red tops and white roots. We shared a piece of Yupo, a "paper" that is plastic and very smooth. It's a challenge to get watercolor to cooperate on it but it's fun because it can be so unpredictable. The other fun characteristic of Yupo is that if you don't like what you have painted, you can put it under the faucet and wash it all off. In fact, the sheet that we cut in half and shared had been painted on several times. So now you have a choice; thumbs up or thumbs down. Should I keep it or put it under the faucet?
