Love the song. I would listen to this for hours.
First of all, the instruments chosen for the beginning are great choices. The buildup actually is quite unexpected to be a buildup for so early in the song. The fact that the music just drops at 2:39 is amazing. The instruments work so well together and combining that with the good note combinations make it amazing. At about 3:24, the song gets a bit quieter which is a good effect for the part. It feels like it's building up so much. This part is good until 4:27 where i hate the part until 4:51 where the other instruments make it better. This part lasts quite long, ending at 5:41. The next part builds sounds peaceful with the piano until more instruments are added at 6:10. At 6:55, the song gets quieter this small moment is amazing and most music developers don't use it. At 7:43, louder instruments break the silence, which is a good technique. This lasts for 30 seconds until 8:08 where the entire theme of the song changes. The vocals add to the theme of the buildup. It gets louder until about 8:45, where it starts to get quiet. 9:04 becomes silent. around 9:20, the song starts to go back in. It has sounds allot like the first part.
