I think you are referring to the repeated "What you've left behind" lines?
I found those a little bland. I think it would help to have something different there to break it up. A guitar solo should work, or if you want vocals, change the melody at that point before returning back to it to bring it home.
I listened to the song and then did a quick scan through
the rest of your songs posted to SoundCloud. To see how
you had handled this on other songs. It would make sense to
stay within your usual treatment for a cohesive solution.
All of your songs seem a bit flat dynamically. And I don't
hear any guitar solos elsewhere. But I could have overlooked
a solo that is there. I like the intro on HEARTBEAT. You could
do a breakdown with a second intro instrumental section.
Or whatever you commonly do to break a song up.
--- EDIT ---
I went back and listened to more of your music.
Are you applying reverb to everything? Or am I hearing
ambient room sound. You might want to try removing most
of the reverb, or using deadening material in the recording room to
limit sound from bouncing around so much. This would add
some much needed clarity and heightened dynamic range.
