I like the melody and the chiptune-esc sounding vibe you've made here. There are some errors that make the song not flow quite right, but if we're just looking at notation, I think you've made something rather catchy.
I think you've nailed the theme as well; it's a very mystical track; I can't give it a high rating for listenability, sadly, but all in all, this is a wonderful track, well done! I hope to see you in future jams!!! :D
