That's much better!
The big tweak first: there's a stop and pause around x20 and then the ball goes up again?
The bounce just needs a few little tweaks! The chart is great and it shows immediately the spacing tweaks that you need to make.
Look at the spacing from x8 to 9. Now look at x9 to 10. The spacing from x9 to 10 is smaller than from 8 to 9, but it should be bigger, because the ball is accelerating as it falls.
The bounce feels a bit soft because you have a very small change from x11 to 12. Frame 12 is not needed, go from x11 straight to 13.
That's it though! Almost there!
