So we were at Wonder-Con and I was watching one of the masters (Jim Lee) at work. I noticed after he laid down a quick rough to position things, he went in and blocked out a lot of the shadows. Here I thought it would be interesting to block out the color and then go back and add some detail. I used the paintbrush tool in Sketchbook set to a low opacity which makes it function more like an art marker. I’ve seen some colorists and artists who use copics do this.
