I really think you could benefit from taking more time to mix your tracks or at least put a limiter on the master or any loud instruments as I can hear them clip, you have really good ideas and songs but they suffer from the same issues.

Piano is good, I’d suggest using a limiter or mixing the sounds better, as you can hear the song clip at parts especially at crescendos.

The song sounded pretty good until the 3rd and final drop, which then blew me away with that unique sound design and melody, outstanding work! Those added pluck sounds really made a great final touch.
