The intro is one of the best I've heard - and first impressions are everything ;)
I didn't think the high pass filter at first was that welcome but you managed to do well with it.
The texture of the song is very good, but I think you may need some more mastering to do as some instruments are kind of lost in the mix.
2:-04 - the chords and the intervals on the main lead were awesome and a really good turn in the song. Again I think some instruments are drowned by some - maybe too much reverb or delay? Great movement of the song, the song seldom became uninteresting as it evolves throughout the song and you maintained the same ideas as it was never too muddled. The only problem I have and this is probably personal preference, but I think you need to maybe EQ some more to make the high pitched lead more noticeable as I found it hard to find a melody in the mix. The reason 2:04 is so good as 1. it's a great turn, 2. is relatively minimalistic and 3. has a nice countering melody.
Overall great work with this tune - it's genuinely awesome and I have struggled to find dubstep songs on newgrounds with this kind of quality (excluding xKore :P)
btw- what DAW do you use?
