Reviewing as I listen...

My initially thought. Bass came in heavy, as well as the main synth throughout.
I like the choice of sounds/synths, I wish the first 30 seconds had a slower build.

The flow and transitions of the first 2 minutes are nice. The kick is present and the snare fits. I wasn't a huge fan of the basses from 2:00 to 2:30. I think some more sidechain compression on those synths would do good.

At this point I'm looking for more variation with the piano and the main synth but it isn't getting too repetitive. The vocals and square synth do add more depth to the main "chorus" of the track.

My favorite part so far is everything at 4:40. I almost wish THIS was how the song started. It has great tension and buildup. I also think it could work as full on drum n' bass. If you'd like. I very much enjoy this section. The mix of DnB breaks with the acid synths and dark melody mesh well.

The outro was dramatic and tense as it should be. As I said your transitions are well made and your breaks and transitions were well timed.

Overall, well done!

My biggest concern was the compression, slight receptiveness of your main motif, wish was a minor drawback and the choice of drums. (I'm a hard ass about drums.) I would recommend getting any of your drums from Black Octopus dot com!

8/10

A mix of a ton of genres, and I like all of them. The breakbeat and dubstep is filled with energy, the trap and "empty" parts are cold, whatever those mean. I quite like 1:03 - 1:28 a lot.

EDIT: While I wasn't looking, this song managed to grow several more minutes and several more genres and styles into the 8-minute adventure it is today. That's awesome.
