"At the end of each week, we can have recognition for those who produced the best quality artwork (by whatever criteria), as well as recognition for those who produced something each day.
For the quantity group, we don't need to pick the "best", we can just recognize everybody who succeeded at the challenge. You could participate without being competitive whatsoever.
But at the same time, if you want to be competitive (or you produce something that is particularly good), you can receive recognition for that as well, independently."
