Sounds really good man. The snare for me sounds a bit dull as well as some of the hats. If it was me I'd try and bring a bit more of the top end out to give it a but more of a 'sparkle'. I really like the kick!
Open massive and have a sine wave in oscillator one. Put a performer LFO on the pitch and set it to how much you want the note to fall by i.e. a full octave or just a few semitones. Then in the performer LFO either adjust the rate of the fall using the rate knob or press sync and choose the length of the fall there.
For those bass stabs:
in the voicing tab: put it on 'monorotate' and 'legato triller'
than in you piano roll, make low note (to where you want your bass to drop) overlap the note where you want that stab/slide to happen (kinda hard to explain, I can take a screenshot if you want)
then, in massive, go to the osc tab and play around with that 'time' wheel. how more you turn it clockwise, the slower the bass will slide between notes.
Play around with that wheel a bit and voila.
