The main bass you have there is pretty cool, but its kinda dry. If you are using serum you can add a phaser filter or a reverb that is automated with a little bit of movement. You could use a different wavetable for the sound. maybe layer it with a low bussy saw bass, and add some stereo imaging to make it wide. The instrumental stuff between the bass is really cool, you should do more stuff with that.
The drop sounds like it could use a bit more juice. It sounds like you have reverb on the basses, which makes tehm less powerful. Instead of reverb you could add some tube distortion to the sound and turn up the sub. dont forget the super saws, put a little minor chord at the begining of each section. It seems like you do have a reverb filter on the growls, you should lower the cutoff to around 20 - 100 Hz so you can get some wacky pitch automations.
The sound design in general needs more stability
