Notes!
I wish the stuttered vocals at the beginning were louder. They're just kind of distracting in the background like how they are now.
In the bridge around 3:00, at least leading up to the return of the vocals, I would've liked to hear more toying with the vocals so that their return isn't so sudden, even just a reverse reverb fade-in thingy *brainfail*.
The second time around 5:00 isn't much of a problem because the bridge is so short.
I don't know what the original sounds like, but ultimately I think you used the vocals well with your production. I kind of want to hear the beats to hit harder and the bass to be grungier, but my first exposure to DnB was the harsh, grungy stuff, so that one is a matter of personal preference.
Ultimately, you pulled this into a seven-minute song that made me want to listen to the entire thing, so props to you for that--I've never been able to make a song that long before. :3 Good on you, man.
