welcome to the forum!! this is cool, the fills (like at 3:07) are cool and the drums are very nice.

i think that it mostly sounds good, but is a little heavy on the high end. specifically, the FX during the drop, along with the supersaw hits, sound a little bit harsh. or maybe its that the bass needs some more presence. im not super well versed in melbourne bounce, so it might be fine, but it feels lacking in low end.

this is really clean overall though, best of luck in the contest.
