Great interpretation! I can hear melancholy/nostalgy there, but also the feeling of moving forward. For me, making song that reflects the author's feeling is the best way to make music, because then the song has got something that "artifical" (songs based on the act of creating songs, not emotions) songs have only rarely. I also think that creating a song without pouring a single emotion to it is almost impossible (unless you're AI). These are only my opinions, I'd like to hear yours!
