Kick is nice.  the beat is nice and filled.  I would watch the timbre of that bass that happens throughout, maybe slap a filter on it even that makes it more gentle at parts.  The vocal sample is a little overdone/used IMO.  Buildup is really nice.  Drop is really unique, very slick.  I think in the main drop the clap/snare could come through a little more in the higher ends, maybe add some saturation.
