It will be interesting if some of the changes stay or become a quick fad. The deep head dips from the ladies are interesting but I can just imagine the back and neck problems those ladies will be facing. Some of the head actions I used to do way back by accident or was my attempt at being artistic are now in style. I remember my instructor giving me grief over it and teasing my artistic actions by saying "some day everyone will be doing it but that isn't today". Hmmm, maybe I should call him up and ask him if today is some day? LOL
Shame you couldn't patent it! Head movements in sync with the dance are a great area for development, they expand the line.
