I really like how your song sounds as a whole. The harp gives it a mystical sort of vibe which definitely matches the picture theme. The harp sounded so good with the arps around 3:36. I have some advice though, when using the piano, you'll probably have to eq out the low ends. I could hear the muddiness from the piano. Additionally, some times the harp felt out of place even though it was the melody. It could just be instrument choice.
