While mixing is kind of weel done, the composition stays kind of narrow and still. There's not much to hear happening in there, and that's the only major problem here actually.
I kind of made a smile for that 'leedling' in the background, but it didn't last as long as I thought. It became a little annoying-ish detail in the track over the time.
I'd prefer you to use more oscilators for your synths, so far they sound very bland and... well... Honestly, it sounds that you didn't spend much time one them for real. Escalation waveform is very recognizable for me, at least.
You need to work more with your tracks, only. More details, less length for different parts and such. No one's actually listening progressive dubstep, really.
