Yes, I work all alone. I have a very specific vision and I wouldn’t feel right entrusting a writer with it. Because I’ve got so many ideas in-flux all the time, I’d probably confuse a writer.
And of course I do all my art. Drawing and inking.
I actually had to learn digital coloring on the fly. I had never really done much of it before so I had to learn pretty fast. Used to coloring took me days on a single page. Now I can usually do a page, sometimes two, in a day if I don’t get distracted. I also do the SFX and lettering.
