What a wonderful idea! Looks like they’ll be calling you up to make the soundtrack for the Sonic Pi documentary 
As for how it sounds. If steady progress through perseverance were a vibe, I think this would be it. I like it quite a bit actually 
My critique? It sounds like a solo project, maybe because it’s all on the piano. Perhaps if you gave each author a different instrument, it would feel more like teamwork!
Keep it up!
