very interesting FM sounds here! i quite like the section at 0:59 where the bass just sits back and drives the beat forward. when the bass is busier it starts to clash with itself so i would turn the release time of that synth down a bunch so it hardly overlaps when you play multiple notes. some of the samples have a click at the end, idk if they're caustic's built in samples but i've never had that issue when i used it, so maybe try making the sample length shorter in beatbox. otherwise there's not a lot really going on and the musical ideas that are here don't really compliment each other well. but i appreciate the unique sounds you used and hope you build on them some more.
