Hmm it could use a bit more ''movement'' with the 808s and you should probably sidechain some things so that its easier to feal the beat. the 808s could also be a bit less lout but thats just me. other than that this is alright
so what I used to do was take notes from the pulv to tune my sub hits (you can adjust the tune on the machiniste). Maybe take the subs and work them for a little more of a bass line to go with the sample you have
The samples work together well (maybe turn down the watery stuff some). I like the idea of the yea flow being done with mario grunts.
