OK, so before I start this review I would like to say that I'm not perfect with my music either. I have some knowledge with music and can't implement it (Due to the fact that I'm using garageband). I really can't wait to see you grow as a song artist.
[-] Suggestions [-]
- Always start with a bass line, chord progression and melody. Once you have those you are ready to create a song. For most dubstep works, it is 4/4 time with 4 chords. Almost always minor unless you are creating melodic dubstep. But I wouldn't worry about that now.
- A good reminder to have is to always have multiple layers of music going on. I have broken this rule myself, but I have recovered from it, and will follow this rule in the future.
- Always have a kick and a (bass?) drum. I noticed you were toying with drum patterns, but they must have at minimum a melody on top of them.
- As I was saying with the drum patterns, what creates a "drop" is actually Moving from the V (Five) chord to the I (one) chord. That is when you use the crazy drum patterns and go wild.
- [Side tip] If you don't want to create actual chords with notes, you can "Cheat" by using an arpeggiator. It is a synth(Ish?) that moves the scale. But I warn you that it only does certain chords. So proceed with caution.
- When creating a chord progression and a melody, it is ok to have some dissonance, as long as you go back to the I chord with no dissonance.
[-] Shameless advertisement [-]

I am currently working on a song that will have a d minor chord, a minor, g minor then an e (Diminished?) chord. I hope it is certainly better than any songs I put out.

[-] Your actual song [-]
- The song was pretty slow to start.
- I personally wished that in the beginning you made the drums quieter so we could hear the melody.
- I also wasn't a big fan of the synth used. It seemed like the pitch bend was too much, to the extreme point in which it came out wrong.
- I also wouldn't have called it dubstep.

[-] Overall thoughts [-]

I hope this helped. I can't wait to see you grow as a song artist. I also understand that I am certainly not perfect with my songs either. Good luck for any of your future songs! :)
