Some flaws:

02:31 - 02:33 - wtf? These sound effects are really annoying to listen to. They are like knocking your head.
Also, in the beginning, saw pads in the middle frequencies don't sound that good and relaxing.
The track really sounds slow despite being 165 BPM until the drop ot 02:40.

Overall review:

Melody - it's dubstep, there isn't much of a melody but it shouldn't be. Although the high frequences pads follow the harmony, that's a plus.

Form - nothing wrong.

Harmony - it's okay, but really repetitive. Try to add some new harmonical someone around the middle of the track.

Sound effects - to me, they are well executed. I don't honestly know about voice effects, should I say they are a bit out of the overall rhythm or not because voice effects are voice effects and I never used them.

Rhythm - nice rhythm for dubstep, delayed notes only represent how they are aiming to each other.

So yeah. The track was decent. But I leave it 4 stars.
