I don't typically like piano solo songs as most people seem to fail to impart the emotion necessary to make solo pieces on the piano sound good (and hence, they end up boring). However, you seem to have nailed it in this. It's very calm, very smooth and very subtle song, with lots of dynamics in the playing, with the mood of the song evolving nicely from quiet and somber to almost happy sounding towards the end. I enjoyed this quite a bit, keep it up!
Thanks a lot for the review! Ill make sure to look at some of your works in the near future.
