Hi Jamagica!! Welcome to boot camp soldier!

Okay, I'm going to give this critiquing thing a shot....I just completed my bouncing ball exercise so we'll see what I got out of it!
This is a link that I HOPE works that might be of some help* on this exercise:

*in this diagram he doesn't show the ball making contact with the ground before the squash which causes a popping effect when left out. (even without the ground though I can tell that you have that part figured out and it's well done)!
-The first thing that jumps out at me is the difference between the 1,2 and 3 frame. The increments of the first fall appear to be the same (probably this is the straight line Rodney was talking about). So you might try starting there, because as the ball falls it should build momentum. (it looks like the rest of the bounces are perfectly fine on this issue, well...from what I can tell...I don't know how to stretch it out all cool like they do.. to see the arches)
-The second thing that jumps out at me is the squash and stretch seems to be off in places. The ball starts out already stretched on yours...but I might try having it start out in its original form at 50%. Then as the ball gets closer to the ground the ball stretches more with the biggest stretch being the frame before the squash. Then vise versa on the way up...have the longest stretch be the frame after the squash and as the ball travels up it approaches the 50% again. (basically what Rodney said about the stretch)
*these s&s problems seem to disappear after the first two bounces, the s&s looks great in the following ones. (it could be adjusted a little but it's not bad at all)
Welp that's all I got right now... but it's looking really good and you do NOT suck!
It's actually not a bad first try!
Keep up the good work, I have found my boot camp thread so helpful.
The people on the forum really seem to know their stuff!
