chord progressions
It is not your fault you did not "discover" this chord sequence first, and so your song and ideas do not deserve such harsh comments. yes it is basic. and so are the instrument presets. however you have executed a reasonable melody and made the chord progression your own by adding small ghosted notes. your understanding of harmonic accompaniment is great too. you certainly have the makings of a good musician.
well done for trying. and for getting over people who have no respect for musicians at lower levels than they. KEEP IT UP!
