I think that its a nice experimentation here, but I'd suggest two things. 1. Although vocals don't always have to be the loudest part of everything, I do feel like chester's vocals can be a liiiittle louder here. I hear you're doubling the vocal notes, but seeing as its also panned center, its making it a little harder to hear his vocals. I would pan it to the side. (usually double tracked, hard left/right). 2. When the chorus starts, the first note played by the ambient instrument comes off as something a bit, scary? (I find) Anyway, don't want to come off as too harsh or anything, just trying to give constructive criticism, keep it up!
