Nice job!
I hate scoring - I never really know how to mark things.
Really good stuff here though - good job with the percussive elements and it's got a dark manic feel to it - you get a 5/5 from me.
I probably should have voted 4 though - I'm sorry but you just know that because I voted 5 it'll go to the top of the pages and at least one asshole will zero it just because... A 4 would attract less attention from the pickaxers.
Keep it up - I'm looking forward to hearing more of your work.
