I don't know right/wrong either. I just have an opinion. I could be very wrong.

Regarding the title, a title should stand out, should be very much the gist of the song. The word 'Promises' doesn't stand out, to me. There's a little bit of it in the verses, the 'oath', etc., but it's not a strong theme throughout the lyric.

The Chorus is weak, actually, not really an interesting making of some point to the whole song-story. The Bridge is weak too, in that regard. Keep it short. And, ideally, say something pivotal in the story-line, giving a finality to it. I cut the bottom two lines. You could cut the top two.

Don't try to keep it about your friend in reality. Make it a simple lost-love song, a fiction.

Again, not declaring 'right/wrong'; just opinions to stir the pot of your imagination.

There will always be another song to be written. Someone will write it. Why not you? www.garyeandrews.com
