Very nice job guys! It's a good example of how a human can tailor the decorations intuitively to make the whole sound better than the sum of its parts. You also end up with recurring licks that create signature turnarounds in the song (which usually doesn't happen with Real Tracks unless the arranger makes special effort to ensure that it does)

There is one vocal harmony note that doesn't sit well with my ears even though it is probably a legitimate note... it just doesn't sound like the PERFECT note to me.

At the end of the refrain when you sing "this is the PRAYER..." you hold the word PRAYER through two chords. the harmony to the word PRAYER during the first chord sounds like it needs to be different but When the word resolves to the next chord, the harmony sounds more pleasing to my ear. I think if you used the second harmony note and held it through both chords it would have more impact.

also in the phrase "Ain't got much but at least it's MINE" the harmony note to the word MINE also sounds like another note in the scale would make a more satisfying harmony

But, this is one of those observations that is totally subjective and could legitimately be seen in multiple ways. This song is so good that any negative comments are kinda like saying "Yeahhhh Cindy Crawford is pretty but her nail polish isn't the shade I prefer..."
