Really cool stuff! It's amazing how the two parts are so different, yet somehow fit together. For the opening section, you could maybe experiment with more 7ths and 9ths in your left hand chords to give them a bit more expressiveness and 'crunchiness', while also enhancing the contrast with the relatively clean texture in the second part. I also agree that a third section combining aspects of the first and second sections would be really cool. Awesome job, this was a lot of fun to listen to!
