the grinding is a little too loud, but other wise its gooodddd
Still kinda odd so far, but its better. I like the grinding effect.
I like what you did with it 
P.S. I’m not completely sure that you noticed the tempo go from 300, to 312, and to 313. Because the last sheet (4) is at tempo 300. I was kind of aiming for tempo 312.5 but since there are no decimals I was going to alternate between 312 and 313.
