Interesting listen. I like the mood, but some of the compositional elements make the tone feel somewhat inconsistent (is this supposed to be in major or minor key??) What I noticed a lot were a lot of weird and unpredictable twists in the melodies, which is great, but would feel more at home if there were some more predictable variants and the riffs you currently have were your B sections instead. What you have now seems like it's a confused half-breed of power metal and progressive, which isn't bad except that some (not all) parts feel a little awkward and your transitions aren't great. The quiet chugging sections also feel kind of pointless - I don't feel like they're really building to the more energetic parts.
Hope this isn't too critical of a review - I actually really liked this piece (2:55 - 3:38 sounded more like a jam session than a song but holy shit it sounds amazing.) There's just a couple hiccups here and there standing in the way of this being outstanding.
