A really good song and excellent vocal performance! There is some frequency in the vocal mids that needs some cutting IMO (maybe 600Hz) as it's poking out too much. Vocals are really nice until about 2:00, then your confidence or attitude changes and the lead vocal doesn't have as much impact. Also about then the harmony vocals change character, pulled in toward center more I think, and getting as loud as your lead (compensating for the lead vocal?). The song loses energy at that point.
Listening a second time, the harmony vocals early in the song, and after 3:00 seem higher pitched and that may be what needs some EQ treatment. In between, the harmony vocals are a bit lower and fit better. Generally I'd say pull the harmony vocals back a bit just to supplement your lead vocal and not compete with it.
The drums in the intro are just a little heavy on the low end. I think that could be pulled back a little. Otherwise, the instrumentation works well.
