This really represents the whole void theme, I think you nailed it! The progression building up and leading into a "softer" type drop with a new part to the melody is perfect for what you were trying to depict, and the longer style of pacing definitely also helps. It's also very rewarding when more stuff finally kicks in around the 2:22 mark (especially that sax, man its cool!). The ending is also perfect after all the song has done. Awesome work, keep it coming!!
