OOOOH! So close man.
Bro..i've done some dubstep in my time and i gotta say only the following.
TRACK NEEDS A DROP!
Whatever starts at 0:32 is NOT A DROP (but your fucken close bro)
I know that it sounds intimidating...but its possible...with practice (which also sounds kind of intimidating)
Try implementing things like Risers, maybe some whitenoise risers or steady pitch shifters..
In my opinion a good element for a drop in this particular track would be a heavy Reverb kick.
But thats my opinion.
The main element is quite catchy so you may wanna keep it as it is. (but change it up a bit for good measure)
But since this is a finished project...maybe you could implement all of the stuff that ive mentioned here for future production.
Food For Thought.
Good Luck.
