One suggestion could be switching to minor scales, which would add more progression to the piece. but its a loop i guess. Idk could create something cool. but besides that the mastering is really good and the tune is great. sounds like a nintendo piece.
Thanks for your review :) I'll see I might work on it a bit more and maybe try adding a minor scale.
Please contact me if you would like to use this in a project. We can discuss the details.
