Here are the next batch of new characters I am working on. Again, these are very quick and very loose. Maybe less than 30 min to do all three sketches. Quick rough in pencil, then go over it in pen ( I like Uniball Vision .7 gel pen), and do an outline with a sharpie. The outline does a nice job to pull it all together and yet still maintain the spontaneous feel. Still, it's important for me to keep things loose like this so that it's open to little changes and adjustments.
I just finished issue #46-- here are some character designs I did for the arc. Quick pencil rough with pen/marker finish. I love working this way-- it has a spontaneity and energy to it that working in pencils only doesn't. I'll have to try drawing an issue like this one day.
