These are some covers I flatted for The Goon from Dark Horse Comics, drawn and created by Eric Powell. He's an amazing artist who almost always works in ink wash. I find that some colorists these days, when coloring ink wash, rely on the gray scaled art to do the job. It kind of makes sense because the artist is doing some of the work that usually is done by the colorist, the tones and whatnot.
But these examples illustrate just how much the colorist adds to the artwork. The colorist here being Dave Stewart. The covers looks cool with my primitive flat colors because the drawings are so good. But you can really see how much Dave adds to the whole package with the finished pieces, especially on the second one here, the closeup of the Goon.
