What I love is the natural flow of it... Up foward and open, to a bend back and forth supple, to collected, to stretch, and usually up again from what I have seen in the clinics. Just a nice flow without tons of definition or correction in each.
He lets the transitions do the work! Or the figures, or whatever he is working ... LOVE IT!
We all can get really stuck into 20 bad circles instead of a few correct and move on.
