Use the stuff in the intro, but cut it in half. We just need a tiny hint of that 'effect' in the beginning, and the loop cut is noticeable. So cut it in half ... or fade it hard to a dead spot, and then hit us with the verse.
I like the vox level in the first verse. The baritone vox doubling panned hard right is effective, but it needs to 'come out of that tight corner' from it's hard right panned position. It needs to be a touch closer to the lead vox, panning a vocal line HARD right or left is 'camp' and it can be 'tacky', you really have to have strong and ultimate justification to pan HARD to right or left, any vocal track.
Doubling a vocal track and panning one hard left, and one hard right is a different matter, that is a good way to develop the stereo field and promote 'chorusing'. This is a single vox you have panned hard, and that can become distracting for the listener very quickly.
Use it only once in the song, and work the voice in closer to the lead vox as you proceed in it's next presentations.
In the pre-chorus, your vox needs to be further out on top of the mix as you have added a lot of additional instrumentation there. Perhaps those instruments are too loud. It's almost ok on headphones but the vox gets challenged on speakers.
In the chours, gently EQ a bit of the nasal top-end off the singer, and give me even more volume. The vocal doubling panned hard left works, but I'd move it in closer as the chorus progresses ... autopanning it to join with ... as the end of the chorus is marked with ... that 'ahhhhOhhhh'. Sweep us into center as the chorus ends.
My philosopy ... the singer's the star, don't ever step on the lead vox, just like you would not step on the lead guitar solo. Without a lyric and vocalist ... it's not a song, it's an instrumental. And some band's treat the vocal as an instrument, and that's fine, but I don't think that's justified here.
At 1:19, this 'thing' is simply happening too long, I'd like to put some freaky - REAL - violin over that, weaving around it, and based on the melodic movement of the verse.
PM me if you want me to collab with you on a bit of violin for that spot.
Vox level at 1:46 is nice. As the baritone joins in, the verse vox is no longer center stage, need to keep it there for the life of the verse. I would have the baritone doubling even closer to the lead vox at this point, because that hard panning is getting a bit tacky now.
Drums are getting too loud, they are in front of the lead vox. The aggressive nature of the part at this point serves the mix, you don't need this much volume on the drums.
Yes, lead vox needs more, and that means bringing the instruments down to develop 'headroom'. Nice drum part, but it's stepping all over the lead vox. And I really feel like the chorus is now led by the hard left panned vox ... and that may be your intention, if so, I would move that hard panned left vox closer to center, and increase the volume.
You could have a very effective 'sweep to center' by the end of the chorus here, if indeed you raise the volume of the hard panned left vox, and make it the lead, for this chorus. I think that would be a really sweet technique.
again, the outro 'thing' is too long, it's kind of cool, but not really, you need some freaky violin there also, maybe even a bit of cello also, and I play both.
I LIKE this tune, I LIKE the performances, and I LIKE the mix, but it can be a very fine mix with some more thought and work.
