Please check my transcription

Hey, I've been trying to get my head around what's actually going on in this piece. If you have a good ear could you look through my transcription and suggest changes/additions. Don't worry about rhythms and timings, I just want to get every pitch on the page. I'm really only after the string cluster and the stabs, the rest is just context.

I hope my notation isn't too annoying: first two lines are treble and bass clefs with the 3rd being percussion. The piece is "Escape From the Farm" from Battlestar Galactica season 2.
