the rif is pretty good, i would however suggest if you can work in a slid in to silence hold and have it come back.
the other think is maybe you should scale a tone down from where the "spin" outs is from the general heavy ones. they fell a bit out of place ( if you get what i say ); they nice, but i just don't know. maybe one note lower ? or have their bpm drop a litte vs the heavy ones
