I love this song, the mixing and practically everything is great. I like the different pads and stuff you used, it's a very advanced and progressive song. Maybe there is a little too much sidechain in some parts, but not an insane amount. Also, I would prefer it if the song had a main melody, but that's just my opinion. Very well done! (Please make Dubstep next!)
Sound Design: 10/10 - The sound design in this track and pretty much all of your others is amazing.
Composition: 7/10 - I do like the composition (especially around 00:58) but as I said, I'd prefer it if it had a main melody.
Atmosphere: 10/10 - The song has excellent atmosphere; the pads around 00:58 are just perfect.
