Interesting song :) It starts with a simple and repetitive rhythm loop - but that's elusive! 'Cause that "simple" rhythm pattern is made of various bits of percussion sounds that brew together and grow into a solid massive drum track, while underneath that sonic "blanket" a lot of things are going on: subtle ambient drones kick in, building an ethereal sound "coat" that push even more the drums, the choir-like synth line adds depth and texture to the song, and just when you think you got the hang of it, it lands a mega drop and then all hell breaks lose - revealing why this was named "Dubstep" - yes, you get that, but also much more :) It's a delightful style collage with a particular spin :) Good job :)
