Beautiful shot. Little blurryness shows motion in the performers. Looks good. Focus is good. I'm glad you did blur out the background too much. It tells the audience where the picture was taken.
Very creative shot. Wish that guy on the top were not falling backwards! Looks dangerous. Color is good. My only criticism would be that there is too much shadow on the fellow on the bottom. A different angle (pun intended) maybe to get more of the sunshine on him?
Some of the angles these acrobats make aren't quite 90 degrees, but they're close enough. You did a nice job of catching their act. The slight motion blur of the top person's legs is a nice touch. The lighting is harsh, but there's not much to be done about that California sun!
