Most of it sounded fine

The vocals were hyper distorted, and I don't know if your mic sucks so bad or you love after-effects. Usually if you EQ crappy microphones correctly, you can't make it sound somewhat decent. I don't know how you would EQ your stuff though because I don't know what it sounds like dry.

Only one word of advice on your arrangement (which is well done), after the computer voice you have some type of distorted guitar midi-instrument. Guitar midi is the worst because it always is the easiest to sit back and say "THAT'S MIDI!" When I heard the guitar instrument, I thought "OH GOD, CHEESY MIDI." If you can distort regular midi instruments, I would recommend trying to distort a keyboard sound or a synth, because those usually turn out alright.
