You were sure making a lot of tracks at this time. I love this because I think it does a great job of capturing a random mood. I really don't know what it is. I imagine it's more sad, as happier songs generally have more going on. It's wonderful to hear how soft this is. You can really tell it's from a flute.
I actually was playing the flute at one point in a high school class. There's some piano, which I did outside of class and which I am now better at. It's nice to have some soft melodies going on. I hope everything works out for you. You haven't made that much lately.
