I think this piece feels like what I'd be listening to if I were looking out the window of an apartment complex in the downtown area of a city while it's raining at night.
For an electronic song, it's quite peaceful. I wouldn't necessarily call it "Dubstep" but for the most part your submission and its various descriptors fit together nicely.
I think it would be beneficial if you put your thought process in your description so I'd have a better idea of what you were going for. That way, I can judge based on how clearly your intent came across rather than my own taste. I could also potentially provide a more accurate rating.
