Mixing Pop is even weirder than general the usual.
So, the zing is melodyne and putting in the even harmonics within melodyne. (Not Full to the right, just a tad). For the rest sooth on the low end of the vocal.
Mix wise you are pretty spot on. It just needs more poppy transitions. Just copy paste them from the reference. No need to be creative.
And get some over the top side vocals for the chorusses.
Goodluck and good job
