heres a dub i started on this morning
straight from the composition, no mixdown ( to be honest, im an eq/compression/frequency novice)
but would still appreciate any comments on the sounds and how i could improve them.
feeling everyone elses work, real quality stuff
cheers

relatively new to dubstep, so its nothing special, but would appreciate feedback and tips on how to improve my sound etc. the mastering/mixing is pretty shody so doesnt sound to clean but its just a rough idea.
