Definitely a nice start, the beat should change, but the buildups are good. I like the intro from 0:00 to 0:10, but the drop is really where some problems come in. The "yoy" sound could be used for some good drops (nice sample you got there, can I have it?) but it is used very randomly. The main problem is depth. I encourage you to add a subtle background beat that is quiet, so it won't distract, but still give tons of depth like a background in a video game. You can also make a quick drum sound quiet and loop it in the background of the drop on every note to add some more depth. I think you should really at least do a different drum kit instead of the default, experiment with the tabs. Also, it's a good idea to try to start small on dubstep. BlueAlpha14 really said a lot of the things I said. I hope this helps you out.

Well, considering you haven't practiced much on dubstep I hope my feedback will be helpful.

First, you should probably get some drum samples. There are eons of free drum samples out there, and most of them are royalty-free to use on Newgrounds. Just a warning, I got my audio portal scout revoked because I used default drum samples and presets. There's no shame in using drum samples that were made by others (as long as they're royalty-free), just about every artist in the world uses them. Stock samples just don't have good quality, because FL Studio cares more about creating the DAW than a bunch of .wav samples.

Second, the melody is extremely boring. It's just ding-ding-ding, over and over. Maybe it would be pretty catchy for a ringtone, but not so much a song. The saw sounds like it was made in 3X OSC, which would be okay except for it doesn't sound very satisfying. You can make pretty decent saws in Harmor, since there's a lot more sound settings than "choose a waveform and *ding* it's done".

Third, the drop is just... well, I don't know how to put it. The saw isn't very powerful, and it's very quiet. It also didn't feel like dubstep. The only based you use was a 'yoy', and it appeared very randomly. I would suggest maybe adding a wobble (and if you have Harmor you can actually make a decent one) and making the saw chords a bit more harmonic.

I do have to give you props because you actually nailed the beat. Way better than my first try at dubstep.

Hopefully you don't take any offense to this review. I'm only trying to give you suggestions and tips that might help improve your production in the future especially if you want dubstep to be one of your main genres. 2 stars for effort.
