This needs to be a progressive track - u essentially began the beginning like a pad break like an intro which of course, i guess is creative style. However, from the perspective of most professional DJ's ( excluding myself) including TYAS or maybe even ALEX M.O.R.P.H., u really want to start the piece off by a string of kicks ( with power ). Also with transitions - I hear so many people using "dead" pauses as transitions - do not use those. Instead use a nice sweep. in place of a reverbkick - which I think u used. And finally for the ending make it strong - essentially break down the song by layers - if u understand.
Thats pretty much it.
