I'm digging the build you got so far. Just a light suggestion to consider is to get those build-up snares in the beginning to have a little more snap to em. Maybe add some light sustain to em and give em 0.5 to 1 db boost either volume or EQ'd and I think that'd really be kicking.
4.5/5 - Really good stuff, some minor adjustments and of course finishing it will surely make this a banging track.
