It's decent--and fantastic for a second attempt! Compared to really good dubstep though, this just isn't that good.
Musically, there's not much to it. The bass really is a little boring. Sounds like a Harmor preset bass...(key word there being "preset" =P)
Nice for a beginner, but please don't let your creative drive stop here!

I like it, it's really good for a second attempt

pads suck...empty space everywhere.. wobbles need distortion.....percussion is lacking.....snare needs more crack and reverb

my fav dubstep is the new genortion

This could be mashed up with something more upbeat. But it's awesome, either way :D
