I'm late to this and went straight to mix 4.
Little lip smack on the right at about :46. A couple more smaller spots late - both left and right.
I thought the vocals, both lead and harmony, we good. Nice tone and singing. Lead vocal level is sitting at a good level. I think some of the backing vocals could use some more layers. They're a little thin when you get to the "ah wooo's". Or maybe it's just the take(s) on them. The delivery could be better.
Acoustic guitars didn't sound too bad. They had a little bit of an auto-harp sound tho. The clean electric guitars were a little boxy.
The bass is a little boingy. I think it's missing some low midrange, or has a low end boost that's too much. The low end is a little rumbly.
