For awesome Dubstep parts, thanks!

Pretty cool, but the production needs some polishing

This is pretty good, personally I wouldn’t start at the drop but other than that everything else is really good!

It could be better. Don't worry, just try to improve.

This is not a typical dubstep song. It's great that you tried to make it sound more original than most dubstep. I'd really like to hear more music like this from you. When making a dubstep song, I advise you to avoid the general structure, which is:

Intro , Build-up, Drop, Dubstep, Post-Dubstep, Build-up, Drop, Dubstep, Post -Dubstep, Outro

But still, I think you need to work on the dynamics.
