Wow. Again the human form is used beautifully and gracefully. I suspect that besides athletics, gymnastics and art, there is a sense of contortionism at play. As for criticism none really but in hindsight you could have thought about the composition. Include the elbow of the girl on the right. You had the space available on the left. Mind you, I would not have envisioned that either if I had had the option to take a shot like this. The bummer is that you have set yourself a standard that is so incredibly high that I am now expecting only perfect shots from you. It is good that you leave a humble spectator some space to point out the very minor hyper critical elements that cannot quite fit the bill as flaws.
