Cool piece!
I get an improvisational vibe from this one. I don't mind the repeated chord progressions, but make sure to really vary your melody if that's going to be your MO. I feel like too many times it's repeated or played in octaves a bit much. The embellishments were nice, but those seemed to be repeated as well.
I really like your pacing in this, the ritardandos and transitions were well done. Loved the change in tempo at 3 minutes, and the ending was a nice touch in major.
One part that struck me as odd was the section with rising chords right before the 2 minute mark. The left hand seems really dry while there's reverb in the right hand. Not sure if it's just me
Overall, congrats on completing this one! For the future, always be thinking about the balance in harmony, melody, rhythm, texture, tempo, etc. If your harmony is static on four chords, really explore the melody, or think about changes in rhythm and dynamics. The list is never ending with how you can develop your music, so ultimately it's up to you how you prefer to do it. That's what makes you a composer imo. Anyone can come up with a melody or musical idea, but a composer knows what to do with it.
Thanks for sharing, and feel free to comment on other composers' pieces. Most will check out yours in return!
