Unnerving!
You've given yourself a really tough task here. There is sooooo much going on in the original piece and I wasn't sure that it would handle a D'n'B beat underneath it all. I think you've done pretty well though, you've boiled down all the characteristic elements of the piece and left enough space for complex rhythms so well done on that.
I think there are improvements to be made however. There is a major clash in the region of 5-7 seconds, also heard in the outro. I know the original is quite dissonant in places but because of the number of instruments playing, it is buried and the listener gets a feeling of unease. In your song there are only two elements when this occurs so it sounds like a bum note.
Also you need to vary the velocity of the violin lead before the synth kicks in. It sounds like you have it at 127 through the whole passage and it makes the violins sound unrealistic. The original is very interesting to listen to because there are so many parts floating in and out. It would be easy to incorporate some of these things into this song.
Your bass sound comes across as a little weedy in places. I think the track could do with a very warm, round sound to fill out the lower frequencies along with the growly line you have there already. Whilst I like your drum beats in general I think there are too many glitches. You have a pattern that you've stuck to throughout and the whole point of glitches is that they're meant to sound a bit random. Throw them around the stereo field a bit, add some filters, chuck in a few one-off breaks and drum shots. All this stuff adds to the movement in the track and would really help in retaining the listeners interest. The melody isn't brilliant (sounds a bit like the chorus of 'Crack A Bottle') so you have to add these elements to make up for that.
