While it's not my favorite I think it's very nicely done. And I don't know what everyone else is talking about but I definately get the calm and disturbing vibe completely

Very quiet

This track seems like it has a bit to many randomly hit keys. You should have tried using a different synth setting because it comes off more unpleasant and irritating in parts then disturbing. It has a calming presence but its hidden behind static. What are those wierd crunching and tapping sounds for?

needs some work

not that good, your saying u tried to to get some where between calm and disturbing, and it just didnt happen. work on your synths, the keys really killed me and the simple drums

meh not bad

but it kinda is, its not really Disturbing, and it sounds like your recording from a speaker to a mic, its a off effect but you rattle it, the slow Synth feel was dull and did not make me the lest bit Disturbing, if you need help on that i got you covered. i thought with a name like Raping Angels, this would be hardcore speed metal but its very lack luster. need some reviser Screaming and like foot steps and like robot clanks with a Raging static feel from a T.V like white noise and dude you need Creep violens or an orgen or some thing. that streched out pad will not cut it if you want Disturbing. it was a calmness that make me twich cus it well bugged me
