that was.....hmmm.....interesting? lol i dont think i can pass judgment on this he he its definetly not my style of dubstep.
Production wise, you got alot of ideas crammed in there, overal it sounds quite cheap***** tbh, like the standard presets u get in fruity or summin. The riff is quite a good idea an the arrangement of the drums are good. Just the overall sound isn't full enough, layering is what your missing, and careful e'qin etc good ideas tho man, an for your first attempt well done!
****Like a midi off a LG ringtone, i swear ive heard this before lol
