Looking at that waveform, I'm scared to see what happens at a minute in!
This is freaking WILD.
I think there's a bit of over compression and sibiliance around the mix. The transients on the drums and the note bodies are getting a bit lost, and the sub is not taking up the space it should be. Crispness is good, but in general you don't want your bass to be crispy, your vocals to be ess-y, and your hihats to be too loud. I recommend finding a reference and side-by-side comparison as you go along. Make sure the volume is comparable to your mix so you can compare.
Otherwise, great switchups and an interesting theme! I appreciate the vocoder!
