The song is interesting. I agree on the vox. They sound disconnected for the rest of the mix. Almost like the "telephone" EQ preset was used.
Perhaps... just thinking aloud here, this song, based on the topic and emotion would be better served as a "more acoustic" melody. Lose the snappy snare and Emerson Lake and Palmer synths. Go for a more organic sound.... fingerpicking, strumming guitars, maybe a mandolin, and if you use the upright bass, something with less of the jazz slides ... more along the folk roots that CSN used in their tunes.
To me, musically, and instrumentally, this seemed to be all over the place, searching for what the song really wanted to be.
