Whoah! Cool! Sounds inspired by Wubbaduck. I don't know if you were being experimental or what, but this sounds pretty good! My thought is that this song is just intro-drop-outro, when usually dubstep songs go intro-verse-breakdown-buildup-drop-verse-breakdown-buildup-drop-outro. Kinda long, but it goes by quick. The easiest way to go about doing that would probably be to make something like this, but with a verse-breakdown-buildup before the drop, then literally just duplicate the verse-breakdown-buildup-drop, then plop down an outro, and finally just change a single noise in the second drop to keep things "interesting." Kind of a dirty trick, but it can still sound really cool, like in Omar Varela's "Mess Up" ft Ghostkilla ( https://www.youtube.com/watch?v=vuBpUecMa4s ), which is probably one of my favorite songs. As long as the noises you use are good, nobody's gonna complain about you repeating sections (and even repeating noises over and over). And, you seem to be one of the rare few who can arrange the noises well, which is probably more important than the quality, or even the number of noises available.
So yeah. Song's too short, but you sould have an okay time dealing with that, seeing as this is still pretty awesome. :)
