Can't really tell what you've changed since it's been quite a while I listened to the old one. But holy SHIT. This is so good. I think the piano is one of the changes? I could be wrong, but it's definitely one of my favorite parts about this. Everything else is great too.
I really don't get why this is at 4 stars - this is genuinely one of your best tracks! You know what this is reminding me of? The soundtrack of Spark the Electric Jester! That's a huge compliment if you know it. Can't wait to hear more of this!
