Awesome sounds! Not too harsh or anything. Just perfect "sounding". Mix is good, bassline is good. Though it does get a bit repetitive after a while, but the change in wobble basses kind of compensates for this.
Things to work on:
-Structure: Have a distinct Intro, Chorus, Outro at the least
-Lead up (Hook): You need to build up to the chorus, e.g layering sounds, patterns, etc.
-Drop: Make them "bigger" lol. Cut the sound like 2-4 or more beats before the drop, then come in with your chorus on top of a SUB BASS
That's just Newgrounds talk ^^ Great song man! :D
