It is really an enjoyable experience to hear this sweet melody that you’ve created grow into different styles and think about how it represents the span of a person’s life. I think you hit the vibes perfectly with sweet and gentle at the beginning, then more fun and energetic in the childhood into adulthood, and then a slow transition to the end. It was creative of you to end with the fade out into the ticking clock to symbolize the end of life. Good work and thank you for sharing!
