Not much to say about it...
It's a pretty cool loop. Too bad it's only six seconds because I hate writing reviews which don't reach the character limit :P.
Anyway, I'll start by saying that I agree with Nomader about making some room for the beat. I think the drums would definitely sound a lot more intense if you give them some more importance. Having said that the beat was very good and you lined it up very nicely to the rhythms of the bass. I think that's one of the best qualities of this loop.
The drums themselves were great, and you chose good samples. The snare in particular was very fitting, and the fast-paced hats really added to the intense feel of the loop. If I had to complain about anything, it'd be the kick, which I think should have a tiny bit more of a thump to it. I'm not such an avid listener of drum'n'bass so I'm not sure if a more powerful kick will help, but it could be worth a try, since at times the kick does get drowned out by the other sounds.
And lastly I guess this loops perfectly so I can't complain there. If you were to continue it, I'd suggest starting it softly and full of suspense before moving on to this part, because in my opinion such a contrast will give the song more of an epic sound to it. By the way, I liked the synth you used in the background in the second part of the loop. Very fitting.
Anyway, as I said, there's not much to talk about. Six seconds, although they're packed with potential, so good luck if you ever continue this!
