This was very much an ASMR audio designed peice using a melody I had written myself when I was 6 years old.
You can download this audio for free if you want it.
These were experiments with particles, trackmatts, and masking as well as precomps in Adobe After Effects CC and I even had to get Adobe to help me in the forums.
I custom made ALL of the particles. It was very difficult to create this because there was a heat wave in the summer and my computer kept crashing or the video card would veto the graphics programs if it went over 80F degrees.
