Wow, great for Halloween especially for this time of year. Great Performance, it feels like you put lots of work into making this good. It sounds strangely like A mix of House+Dubstep, Overall
Overall Dubstep getting picked as 1st place song 700 in 1,000,000,000
For your first attempt it's pretty well done. But just for your 'wubs': You should try to get them more bassy. They are pretty much present in your song (hence dubstep) and that's why you should bring more work to it.
Otherwise this isn't really bad - good attempt :)
Keep on going.
