Not really liking that wobbly stringy synth there. It's a little too wishy washy for me. Needs a stronger attack.

0:49, ooh, transformers noises. If this were not mixed so loudly -- I can hear some saturation/clipping. That, or you could probably stand to notch out some high frequencies. It does just sound throughout like it was mixed a little too loudly and a limiter put on.

Protip, before you apply FX to the master channel, make sure your track peaks no higher than about -6 dB. If your mix sounds good here, it's ready to be mastered. It's hard to squeeze a track under -6 dB when you're used to mixing everything all the way up, but it's worth it.

Stuff like your vocal sample, that pre-drop wubby business that delays out of the picture, all that is mixed way too loud and is contributing to the slightly unbalanced sound of this mix, eventually even drowning out your drums. That's not to say it sounds bad -- actually love the driving rhythm of that bass and the synths you've used. May just want to take some time to study some mixing/mastering tutorials. You've got the basics of good dubstep writing under your belt. Can't wait to hear you grow as an artist. :)

This was really fun to listen to. Good samples and overall pleasant sounds, with lots of energy. A tiny bet repetitive at some points, but there are enough layers that it feels like you can pick up different things with each repetition.
