The beginning is calm, repetitive and lasts +/- 1 minute. In the end it is dissonant, but I guess you wanted to make that way. After that you change to stage 2 with a sudden change that makes the listener feel uncomfortable (IMO) . Then you get back to a mix between theme 1 and theme 2 that goes until 3:30. Again repetition is what comes into my mind. I define the rest of the music until 5:00 as some sort stage 3, which then makes a natural jump to the end of the music which I enjoyed.
I am not a fan of this music type, and it seems to me that repetition of patterns is the main ingredient. Anyway, ignoring the fact that my vote intention is "evil", I can see that this gave you some work and as a musician I hate to see 2 weeks of work destroyed. 8/10 and 4/5.
