The "Bwohm" growl that starts at
0:30
is mildly repetitive, change up the frequency of which it comes in and possibly add some more midrange to it. It's kinda hitting both the bass and high frequencies, but it sounds very hollow, and not a good hollow. It needs to be filled.
the change is too much all at once at
00:28
Try using a slope with a lowpass and layer all of those sounds. make sure to lowpass the whole board, not just one sound. It will sound super sweet! also get a kick with reverb and a swoosh noise at
