Cool concept and great drums!
I notice that the middle bass you play with the Pulv over the sample doesn't match the bass of the sample tonally.
The sample seems to play F, A, and D in the original tempo of 90bpm and A#, D, and G at 120bpm (raised 5 semitones) .
Your bass plays throughout C which forms a tritone that sounds dissonant.
To make it fit, you can raise the Pulv notes by 5 semitones, i.e., A#, D, and G (at 120bpm project tempo).
