not entirely sure, but using less big jumps between volume levels might be a good start.
it feels like you were applying random volume variations, so it gets really hard for me to focus on the composition and the atmosphere
i mean, there are jumps from v42 to v62 back to v39 back to v56.
changing this to v54,v62,v52,v56 for example sounds less irritating (imo).
i also dont really like the fm bass/string sample. the sound of it feels to harsh and anggressive for a chill composition like this one, though thats completely subjective and someone else might think it fits very well
