I like the atmosphere at the beginning. Has a bit of an ominous mood. The pads in the background have a bit of a harsh edge - couldn’t hurt to take off a little treble in the equalizer. I like the bass and kick that come in at 1:05 - they add a lot of tension and drive to the piece. It’s very slow to progress, but has a good sense of climax over time. I think that bass is overwhelming the kick a little - I might suggest some sidechaining, or simply stricter equalizing and compression. After the bass and kick cut out at 2:09, the piece loses its sense of direction a bit. I think you need more melodic content - or even simply more moving notes - during the first few minutes of this piece. The pace at which it changes is typically very slow, and when it does change, the transition is very sudden (e.x., 3:28). I also think the mixing is a little strained at around 3:30 and beyond. It’s hard to hear the kick. You might want to scale back the reverb a bit - that could help clean things up. The clap at 4:33 sounds a bit weak - usually claps or snares that play on the off beat in 4/4 should be the loudest instruments of the mix, and this is no exception. The hats there also sounded a bit cliche. Overall, there isn’t a lot of rhythmic variety in this piece at all. There are a lot of straight ⅛ notes between the harmonies and melody lines. I think you need some stronger melodies with more rhythmic variety and directionality. I liked the melody at 6:15, even if it was a little simple and repetitive. Couldn’t hurt to bring it out more in the mix, either. I really don’t think there’s enough material and variety here to justify the piece being over 10 minutes long. At the very least, you should use more dynamics and phrasing to give this piece a little more shape. There was another awkward transition at 7:53, and some dynamics changes or filtering leading up to it could help foreshadow the section with increased energy that follows. Overall, I think your main areas of focus should be cleaning up the mix and consolidating your ideas in the composition to speed up the pace. Keep at it, man.
