Wow, I love this music, it's so atmospheric and beautiful! The opening really got me hooked, and the way you develop the piece further with that secondary theme starting at 0:45 is just fantastic, providing a great new texture and rhythm. Just some minor nitpicks, I did find the music to start feeling a bit repetitive starting around the 1:15 - 1:45 section, I think it might be because the underlying bass lines and rhythm is remaining a bit too consistent from the beginning to that part. I love how the section from 1:45 provides a new palette of sounds and a fresh more open rhythm, maybe you could introduce that earlier to help keep the listener's ears engaged with your music even more. And one last small thing is, I think you could adjust the choir in that 1:45 section to be a bit quieter, when it's at the peak of its swell it sometimes crowds out the other sounds. Overall though, I really like this piece a lot, amazing job!
