The first time I heard this was on the internet computer...but them yesterday I was in the studio, so I pulled it up on the monitors, and that's when I could hear just how tight you have the L/R image. It wasn't apparent at the internet computer, since everything is kinda mono-ish due to the small speaker spread.
Anyway...I can see that the most you had everything spread was about 10:00 - 2:00...which seemed a bit too tight.
My studio monitors are spread about 5.5 feet, so I can really hear the stereo imaging.
What caught my ear was that your lead vocal is off-center (which may be intentional) and it sits at about 12:30-1:00...same with the lead guitar.
The other thing was that when the chorus kicks in...the vocals are pulled to the opposite side, to about 11:00-11:30...maybe that's just the level of the second vocal level doing that when it comes in?
It's all personal taste and everything...I just would have maybe opened it up a bit more, but then, I've always been obsessed with wide L/R mixes.

Not saying go full LCR...just maybe a bit more width, with the lead vocal centered (if you weren't going for that Beatles thing

).
