really cool instrumental. I've used synthesizer v myself for my own music and I like how you've applied it here, but using it for prog metal is really testing its boundaries. weirdly enough is like the vocals progressively get better and more natural sounding as the song goes on, they start kind of rough but end wonderfully. pronunciation is the main thing that stands out, such as "you're shaking" turning into "ya shiking". for synthesizer v, you have to do a lot of manual editing to make it sound more natural.
overall, great job. great composition and production plus a really cool theme.
