Man, this is really good!
I personally don't understand much about mixing and recording... I agree somewhat about the vocals being a bit lower than the instrumentals, but it would seem intentional to me. Your lyrics are very strong and significant, but the combinations are even more. The words evoke the concepts, but the instruments evoke the emotions. I simply LOVE the way your main voice blends to the backing vocal and the melodica (I'm guessing it's a melodica) sometimes, like from 0:42 to 1:05, for example. It is soul lifting!
I'm Brazilian, and for me the use of the melodica really brings some Brazilian northeast folk music to mind, but suddenly your American accent english comes in (spotify told me you're Canadian, but I'm not that good in identifying accents ?), and suddenly you use timbres so common to me, that being the guitar, the melodica and voice, and transforms it into something ethereal. The sounds may be a bit unpolished, perhaps, but it makes me feel closer to you and your composition. Thanks for sharing it!!
