That's a sweet tune John, very pleasant listen. That recurring (flute?) motif is nice, I was waiting for something to play a harmony to it though, instead of unison. Bass lines are nice, drums are good too.
I think the 'weird' thing with the ending is not so much the way it fades, it's that (to me, anyway) the last part after the silence at 4:07 sounds like it's from another tune.
