I think the location of this dance video is very effective. They're using the Dancing with the Stars stage decorated with lots of trees and Christmas decor so it's enough to set the scene without distracting too much from the dancing. And they're able to use the light features to enhance the performance and entertainment value.
This photo is another comparison of ballet versus football. It shows how the football player may have flexibiltiy, but the dancer also has technique on top of that. She is taking the kick to the next level by working on her alignment and technique. Similar to how Billy Elliot goes from boxing to ballet by taking some of the ideas he previously learned and refining them.
