I was liking the visuals and I was following along with the song until I got distracted by a typo on your end. "That we walked in different places," should be "paces." My biggest gripe is that it seems you didn't do your due diligence in analyzing the song while animating. Based on the lyrics, it isn't about losing a lover through a death, but rather it is a mutual understanding that lovers eventually drift apart, i.e. merely a break-up.
