Your arms are kinda stiff each flip, and you start to twitch around in the second one. I didn't like the pose in both of them. They looked kinda stiff to me. The flow in between your flips were good, but try to do some other things besides just backflips and handsprings. It gets rather boring with someone doing the same thing over and over.
Overall a 7/10 It was good, but I got bored soon after. I'd like to see more from you, and maybe something even better ;]
