Friendship is good.
I'm really liking your ambient stuff. (I use the term ambient lightly, I know how it is when picking the songs genre and nothing is quite close enough.)
Great contrast from building up to playing a more down tempo theme. Drum's help the song flow, a bit like well done punctuation.
Piano's chord progression is what sold this song to me.
I think a bit more of a finite ending, or cleaner loop would have been great for this, however, as is, as an mp3, it wouldn't normally loop into itself, so I guess thats just a matter of NGs setup.
