The mix sounds fine.
I AM an old time pop-punk fan. Bands like the Muffs, Goops, Blondie are all fantastic. Excellent music.
Somewhere in the 90s, bands like this and Sugarcult and so many others ruined the genre. They didn't just not bring anything to the sound, they actually destroyed it. But, that has nothing to do with your mix, that sounds great.
If you ever want a real challenge to make something strange sound good. I'll send you one of my tracks.
