That free piano sounds great! What is that?

I find the SFX just a bit too loud for the piano to sustain, especially the occasional thunder cracking.

Sonatina violin -- or cello -- sounds a bit much too dry when it enters. Also lacking those breathy, sibilant pieces which could set it apart from the rain foley.

I really have no other critique aside from the track itself being fairly repetitive up until the outro at 2:15 or so and not really being able to emotionally engage with the piece. It's almost monophonic and does not seem to really progress. Was hoping for a more bombastic -- or even smooth, flowery section before our rather somber finale.

No points deducted for this as well, but that's a really long silent tail. I try to remember to always cut those in audacity or something once a track has been rendered. :)

The sound quality and effects are really nice. I also really dig the somberness of this piece. Main criticism would be that it's rather slow and simple, and for something like this it makes sense not to have lots of complex melodies, but you could have done a lot more with chords just to introduce some kind of complexity.
