This started out as practice to work on my almost non existing animation skills. At first I just wanted to get a realistic ball bounce going, but after a short while I decided to make it a bit more interesting so I added the question and exclamation marks. Once I got that “finished” I decided to try and incorporate it into a scene. And once THAT was “finished” I decided to work on my After Effects skills and try and get it as realistic as possible.
But I know that I’m not even close to being an animator, so let me know what you think

“Final” rendered and composited version:

The background is just an HDR , I’ll probably try a different HDR of higher quality later, this one was only 2k I think.
I’ll be rerendering it soon when I get some time.
