DISCLAIMER: If you are @sejalscratch-2020, please scroll down all the way. Otherwise, please don't. Possibly improved? I made it look less like it was just cloning and more like bubbles were floating slowly on the screen...plus, I added a glow effect since the background was black. In addition, I added a transition and bright mode. Note to @sejalscratch-2020: In the collaboration, the music was upbeat, so I made the particles go fast. Plus, the soundbars were mostly blocking them, so it didn't quite matter that they looked like they were just appearing out of thin air. However, this outro has gentle, slow music and a plain black background, so I felt slow, gradual particles with glowing effects would do the the trick.
Thanks to @sejalscratch-2020 for the original! I just improved it a little. Music: Bensound-Once Again
