This is a NGADM "Round of 16" Review!
It looks like I scored you the lowest out of all the judges. That's always a bit awkward when you have to leave a detailed review too. Well, here goes.
I guess some of it is personal bias, I find lots of the sounds in dubstep quite jarring and unless you mix it really well they come off quite harsh. Your mix is good, indeed. The drums are full, the backing synths are awesome and I love the lead sound, so awesome.
Sadly during the signature dubby bits (if that's a thing) I feel like you underestimated the power of a pure synth to blow out ear drums since their perceived volume is so much higher than a complex sound. What I mean by this is that an electric guitar won't sound as loud as a sine wave because its sound is full of harmonics and the distortioin throws those all over the place too whereas a pure sine wave or something similar seems so much louder.
tldr: What I'm trying to say is that I had to turn your song right down to listen to it, not because it was loud but because the differences from moment to moment in perceived volume made my ears hurt.
What I did like is the variation from section to section. I also think you're really good at making melodies and backings that fit really well together. That backing wouldn't have been complete without that melodie and vice versa. Complete synergie between the two.
Congrats on making it this far in the competition, it's been really tough and you did admirably. Keep it up!
