Here are some of the sketches I have been doing in between trying to finish two more covers for DC and finishing off a wraparound cover for Abrams books (I'll post all three covers just as soon as they are finished and approved).
These sketches were roughed out in blue pencil and then finished off with Pigma pens. It is a lot of fun throwing some heavy blacks in there every now and then. In fact, back before I started working professionally and before I moved into a primarily fine line style, I attempted to draw with spotted blacks here and there in an attempt to find a "comic book" style, which I believed was necessary at the time. Some remnants of that early fumbling around are still apparent in my earliest published work.
Maybe someday I will take another stab at drawing a story with spotted blacks. I'd like to think I got better at it, but when monsters like Mike Mignola are out there, maybe I'd better save the ink.
