I love the melancholy mood here. This piece just seems hauntingly tranquil, small, and apprehensive. The harp sounded a bit too robotic and straight-ahead, though. I might suggest you humanize it. I could definitely see this as a part of a videogame as well. I like how you return to the bare-bones harp arpeggios at around 1:25, too. It gives a solid droning ambient quality to the piece but, again, some more humanizing could really give this piece a new dimension of emotion. Still, it loops well, has a great atmosphere, and uses some heartfelt instruments and progressions. Well done! ;)
