You're right, the vocals drown in the mix once everything sets in. It gets better, but they're pretty much buried for a while. I also feel like the kick is a little strong throughout the track. Nice clap though, and a lovely melody!

My suggestions:
- lose the distortion on the vocals in the breakdown, it just makes it sound like she's got a lisp
- try and re-do your volume levels, starting with the vocals (I'd probably start them at -12db) and then bringing all your other elements in. make sure the vocals stay clear and audible throughout. sidechain the chords to the vocals if necessary. also pay attention to the bass and kick levels
- maybe look at the chord stabs' attack, see if something softer would improve the track

Good luck!
