Very good!
Hey there,
Wasn't too sure what I was to expect from this when I first saw the title. However, I was pleasantly surprised. You've succeeded in capturing a "lonely" and somewhat "eerie" feel, which works out really well, even though it's "just" a piano playing.
However, there are a few minor flaws in this piece. For example, the notes used at 0:39 sound a bit out of tune. Apart from that, it was also a bit too short. I think you could've done a lot more with this, to be honest.
I do like how the piano sounds all natural, though, and that the song is well polished. Arpeggios always sound nice too.
All in all, a well earned 4/5 and 8/10.
Keep up the good work!
