you have a good sound sound there mate. but you could do a lot more with it, no offence. you have a good structure. but if it was me i'd put a few more low end syths in to bounce off the main synth you have cuz it's nice and dirty. plus a few added sfx would help the flow a bit, like a nice airy crash or a mean thud every four to eight bars when the dubstep kiks in. also i think the mix could be a bit better towards the end the rising synth at the end seems to drown out the main sound. but you've faded out so it's maybe just the way it sounds when it begins to fade thats thrown me a bit. but like I said you have a good structure mate i think it just needs a bit more refining. hope you found this helpful bud. :D
