I like how it drops sort of softly into the dubstep section without any kind of hard break or build, makes it sort of fluid and trippy. I like your intro on this one, catchy melody, but I feel like at around 1:00 when you build it up, it sounds too much like you're going to drop or break right there instead of repeating, and it just doesn't flow as smoothly as it could. Another thing you might want to spend some time on is adding more percussion to add more rhythm, and maybe another high-end synth to give some more atmosphere. Other than that this is sounding very good so far, pretty catchy. Might need a break section or a bridge, but catchy.
