Nice! I love your music, and your mixes are always a pleasure to listen to. I almost hate commenting nitpicks because it's a great song and a great mix.
But, here here they are:
This first one is (I think) the most necessary. Pitch correct the last note of the chorus (Before the bridge) and the last note of the song up a couple of semi tones so it's on key (the "you" in "all of you"). I think correcting to G would do it.
The rest are spectral comments. I hope I've been able to tune my monitoring/room well enough to be hearing things more accurately now than before.
I agree with some of the guitar comments. They are maybe a little too biting and don't have enough pop. Also the snare could use a little more pop as well.
It's a little bit sharp/cooked in the highs. 14k ish and 7-9k ...
I think the mix is pretty wide (a lot of the mix seems to be in the side channels), so the vocals are getting a bit buried and it gives the guitars a kind of that fake '3D dolby sound' feel, if that makes sense. If you mono the mix, you can hear that washy echo/phase in the guitars more clearly. It's not terrible by any stretch, but it's there fyi.
These are nitpick for sure. great song. great mix effort.
I did some quick fiddling in Reaper and attached it. the main thing was a HP filter at 39hz, boost the low end at 61hz, then some notches and multiband compression in the highs to try to smooth the sharpness. I also boosted the side channel with a wide Q at around 190hz by 3.5db to try to focus in on the snare fundamentals while giving the guitars some pop (I maybe over did that one), and a 3.5db cut at 4.5khz in the sides to try to focus vocal clarity up the middle.
