The core of the song is simple, which you did well to build off of. You provided a unique sound and taste without it accidentally sounding too over-the-top.
One word: GREAT!!!!! :D
I usually don't check out dubstep on this site because so much of it is cringey as hell. But I somehow clicked on this and said "fuck it, I'll give it a listen." The major thing killing me is the drop. The fact that it's got brutal sounds doesn't bother me; in fact, that's what I liked about it. What I didn't like is that the drums just got so weak. If you've never heard of sidechaining, you should look it up, because that would have really helped in this mix. It's still a good track overall, but you've got some room for improvement. I give 4 in the review, but I'm going to vote 5 because I absolutely love the chiptune vibe you put in this song.
