This turned out pretty awesome! In general AI art is pretty bland, (or horrifying if gone wrong) but I tend to enjoy the stuff creative people can do with AI music.
This really nails the genre of "anime opener" theme music. I like that you had a verse for each character and that the chorus was about the protagonist, which obviously added a lot of length to the song and made it more difficult, but helped to make it feel complete. You also did a good job with implementing the overall themes of physical and personal growth into the lyrics. I'm impressed. Thanks for sharing this with us and the fan community!
