I'm very glad you did something a bit different. The production quality since the days of say, Intrinsic, has definitely improved, but I can still hear bits of both of your styles!
The use of the vocal clips reminded me of Rameses B in a good way, and the percussion was definitely working.
The only two (hopefully constructive) criticisms I have are firstly that the piano is very close on the sound stage, which is good for stuff like pop but for both energetic and expansive themes, a reverb drench send or some stereo widening could go a long way. The piano just wasn't quite as grand as I *personally* prefer it but you know, it's your piece.
Secondly the bass wasn't optimal, I LOVED the pacing of it, but generally in DnB the low end is brought up a little more, sometimes with very slight sidechaining from the kick which gives that same awesome pulse you pulled off. At least you didn't go too loud with it, I guess.
I'm just saying both the good and bad because I know this was a bit different for you both to do, so setting out what worked is good!
Nice work though, that's why it's 5 stars to me.
