You really run into the song right away when it starts! I wonder if it wouldn't have been better with a more gradual beginning, short or no, just something that doesn't completely overwhelm you when it starts.
After that though, when the beat kicks in and the keyboards start running and everything builds and builds... it's pretty intense! :D Bouncing in my seat as I write this, really enjoying the ride and energy. It slows down in a way that doesn't break the focus or fluency, and keeps grinding away, phasing into similar but new patterns and percussion... it's hard to find any flaws here, but if there's something I' think it might be the beat. Considering it's such a fundamental part of DnB it might be nice with some form of change there. Though it alternates, there are so many alternations with the drums, and it always has the same backbone to it. A solo, or more noticeable change percussion-wise might bring it to the next level. That and possible one or more bridges, though I enjoy how consistent this is too.
Keep it going!
