I love the style of music, it's a creative instrumental with tempo changes and true song & chord progression. Overall tone of the song strikes me as a reflective, technically-oriented song which I like vs the factory manufactured pop stuff that comes out on the radio. Other notes:
* Sound quality is great
* I like the use of bass i.e. around 2:12 and beyond, creative, it almost has its own melody like Rush / geddy lee
* Inventive song progression
* Good mixing job, balance of instrumentation.
