Personally, I've almost always prefered the sketchy, shady, black and white style of an art piece over the full colored version of the same piece. Sometimes my preference depends on the art piece, but I have to say that this would probably be one of those pieces where I prefer the sketched version over a fully colored version. I love the shading and how there are actual differences in some of the shades (some shades are darker than others) and I truly feel that the art style of the sketch matches that of the show. I think you did a damn fine job, my friend. My only complaint is that I'm not really into the ideas conveyed in the drawing, but when ignoring that ideal, I like the overall look and style of the illustration.
