Are you sure you moved every joint ? Chavo's hands were pretty stiff, same for DH Smith.
In fact, it didn't look like a frog splash, but more like a basic splash.
Anyway, although, it was a nice try.
There was shadows, and camera was a bit shaking.
It needed a rope bounce, but I know that the crappy Mattel rings can't have rope bounces.
Try to change them.
I didn't see any string, but I saw a finger or two I guess...
Bending figures joints more and taking a lot of pictures, could really pay off for this.
Reaction was meh. It was really stiff, and obviousely, it needed more work and pics.
Your string work still needs practice, so practice it more by animating the basics (Swanton Bombs - Moonsaults ...)
Try adding those extra touches such as taunts in your next ani, it'll look more realistic.
If you follow the stuff I said, you should improve (:
Good luck!
