Hi,
I am going to be maybe a little rude, I'm sorry! But I'll tell you the things I would do differently, but it's your song so don't take it too serious or something:
First, I like the guitar, it's simple though nice strumming. Maybe the voice is a little too loud.
2 - it sounds like you use the same chord on the couplet's first and the third line. I could be wrong, but if you do; I would use an other chord on the third line. In my opinion, it gets a little bit the same because it repeats itself four times.
3 - when I first heard the chorus, I felt like you were running oit of breath. When it repeated I realised you weren't. But honestly, I don't really like the chorus. I do like the melodies, but I would sing longer "ooh's" and maybe one sentence. Maybe "the white man come"? Although then you use it pretty much. Just an idea. But maybe you did the short "ooh's" because of the song's setting?
4 - when the bridge came, I could hear that because of the melodies changing and stuff, but the lyrics seemed to me like a kinda "plot twist", which I like; but why dont you sing a little louder? You could create suspense by singing the song 'to' the bridge, like that's the peak you've been building up to from the beginning of the song.
5 - the end is a little abrupt, but that kinda fits the song. The shot at the end does good.
I may sound critcal right now but don't get me wrong: I like the idea of your song, the lyrics and melodies and guitar, just a few things!
Love,
