I am not sure if this is true of your other piano pieces, but your dynamic balance between the melody and accompaniment is poor. It sounds as though you have them both at the same dynamic level when the melody should be brought out more in high relief over the accompaniment. Although there are many places where it's not clear which note is most important, like when you have chords in the right hand while the left hand plays crazy figurations, or when the right hand has figurations where it would be total overkill if all those notes were played really loud. I like your ending chord - it does sound tragic. And your use of the Mixolydian b6 mode sounds quite magical. The first time I heard this was on YT and I actually noticed that you used the La Folia schemata - how did you find out about it? Have you studied other schemata? Great job overall and thanks for sharing!
