Pretty much the whole thing man, i think ur pad is taking up alot of space, and that bass is too high in the freqs and needs to be deeper it lacks sub, maybe use just a sub imo. and eq the bells above the pads as they are both using space in the mid area, + the bass lol.
and the drums dont really kick thru all the mud either, will be better probably when u clear out the overload-mud
some really sick production tricks in here, i liek those. but the mix sounds packed and its leaving the drums pretty squashed down IMO, they need to cut through. snare and kick could be much more snappy, are you trying some EQ and compression tricks on those bitches. other than that little thing - i like this
