a good concept but quite monotone imo try variating your breaks more (yes you do it, but only very little), try inserting other breaks here & there, rearange the loops further add more elements besides the guitar for insperation check out: -Drumcorps (more breakcore then dnb tho) -bazooka (one of the first to combine hardhitting dnb with metal on his label aural carnage) -enduser (I think he made 1 metal/dnb track for some soundtrack) -pendulum (but those guitars sound cheesy/poppy, not my thing but they also add guitars so worth mentioning) cheers
