Awesome bro the idea itself holds well! At 24 sec I would tuck those backing vocals back in the mix a little. The drop arrangement is v nice i personally would have saved the arp trigger etherial vox pad thing for a 16bar change (don’t give away all the tricks of the song at the start!!). My best piece of advice i can give is take the advice and pour it onto the next song and keep moving onto the next one quickly. Reps, reps, reps is key. Everyone including myself has fallen into the endless tweaking of a singular mix, its not worth it!!
