In that low register, it's difficult to understand/make out the vocals. I would consider pitching it up. It was easier when you went up and octive. But it seems like some things are competing with the vocal frequencies in the middle, maybe look at panning as well as perhaps some EQ treatment?
I really like the piano, and the electric guitar, BGV, and your arrangement there at the CODA/Break, a bit of an Elton John vibe to me. But then the vox drop back in to the abyss.. Maybe you could modulate there?
