With choice of going with piano solo you managed to underline a sense of isolation, longing and fragility, and it all feels so human indeed.
The minimalist approach doesn’t diminish the prettiness of the melodies, and despite you saying otherwise your playing works and brilliantly at that! Good sprinkling of some discordant harmonies here and there, too!
The only nitpick is that I would’ve charge it with some little depth FX in order to give it a minimal winter ambience and therefore more “weight”, but your composition skills make up for that. Splendid!
