think the kick and snare dont sound AS good together. theyre both sounding good, but somehow the flow is missing, maybe make the snare a lil bit longer and pitch it up a bit?
as for the rest of the tune, i agree that FX are missing. put in the one that leads to the second breakdown right before the first drop. mixdown doesnt sound that bad and i like all the stuff you got going on. but somehow, the "sound" is missing. everything is just there and you cant decide what drives the track, and everytime something goes out again, its missing something. maybe make the leadsynth louder and sidechain it a bit to the snare? you defo need some hi hats in the intro aswell as some more drum fills and transitions, esp towars the end.
not a bad track tho! big ups.
