The percussion seems a little harsh for chillwave. Maybe give it some more 'verb to distance it from the ears? Possibly turn it down a notch too, especially since it's the same thing the entire time.
Actually, when the rap and choir come in, the balance is a lot better overall.
The side to side panned percussion is too vigorous for me. It's a nice effect but I wouldn't have it on the whole time. I like the vocals and the vocal effects. The harmonies and blends sound great to me
