Like someone else said, the beginning with the bass merged with the thunderclap is really fantastic. I was vibing with the first and last sections, but I wanted a bit more out of the synth melody in the "B" section right before the energy picks up again. I think it just could've used a bit more rhythmic interest and maybe ask as more of lead-in when the drums re-enter, but I think the texture works well as a palate cleanser for the harder parts of the song. I also think the mix is done quite well, with nice clarity from the different parts even when there's a lot going on. Nice job!
