I have found that, for me, creating a course that appeals to students as well as helping them learn is really an ongoing process.
I create a base file that I believe will work, and every session I add to it, or take things out that didn't work.
I have also felt that, for a creative based classroom, giving live feedback on the previous "rock stars" in the group during a Live Chat helps foster discussion and tremendously boosts the drive of all students, because soon EVERYONE wants to show off their own skills and be critiqued.
