very chill, calm atmosphere, the melodies are lively and relaxing as the volume goes up and down, unlike going straightly like a matching ;)
one thing to remember is to have some fades, at the start of the audio, I hear clicks, which means it had no fade in. Also, I hear clicks from the melody as well, maybe it was a lack of attacks.
when you have the instruments play, you should reduce the volume of the background, else it'd crash to each other
