This song reminds me of etherealwind! Classical music with piano is my favorite type of music!
I like the seventh chords in the beginning. Those chords sound great together, but I rarely hear them in popular music.
The christmas sounds seem like they don't belong. I associate those sounds with happy, major chords, but this song sounds like it can be played during mourning.
The harp sounded serene at first, but due to the mixing, it sounded fake once it reached the highest notes.
I like the chord progression with the strings, however, it overpowered the piano. Your selection of chords is amazing; they create several different moods within the song. In my mind, these moods reflect the sadness for the loss while also highlighting the accomplishment's of this person's life.
The ending was underwhelming. I would have liked to hear something more explosive to emphasize the mournful mood.
I like the piano playing, melodies, chord progression, and instrument choices, but the poor mixing detracts from the experience and the ending leaves me feeling unsatisfied.
I hope you feel better soon :D
