There's a lot of work and potential in your song. Some parts are reminiscent of "America," and the flute blends very well with the style and the song. However, the drums are barely audible, and it seems like you were more comfortable singing the choruses than the verses. Honestly, the choruses were very good, and with one or two more voices, it would have been fantastic. Often with "Band in a Box," the accompaniment can feel linear; you have to try to break that up by adding contrasts between the intro, verse, and chorus. It's not always easy, but it revitalizes the song. It's a bit like theater; you change the scenery. The video is great. The advice is only binding on those who watch it. I just wanted to say that you did a good job, and taking on the subject of war for a song isn't easy, and it's better to sing: "I love you forever."
