1. Too many shivers! Fear of the unknown comes with unfamiliarity. The drone was good and didn't get too loud or too soft, nice.
2. I liked the idea you had starting with the octave and then the minor 9th, but you never really completed that thought, just an idea. Quarter-serealistically, your upper F's and G's don't have enough impact because of nothing to really compare it too. You're going to want to figure out the PIC's of everything starting with one, and going up to 14 or 16.
Overall this reminded me of playing Resident Evil 4 again; no easy feat. Nice!
