In its simplicity, there's a beauty that shines like a diamond in the desert. This piece is fantastic, it has everything it needs to provoke an emotional response from the audience, reminding me of Chopin's nocturnes so much it's almost a crime. The somber sound of a lonely piano, like clockwork behind a broken glass.
There's honestly nothing I could really nitpick about this. If anything, you could try to bring more variety to the structure and leave space for more variations. perhaps by introducing an additional theme that could intensify the drama, it would have been a welcomed element in your otherwise nicely performed composition.
