It's a probably a mixture. The long term timeline stuff tends to be scripted. I'll have a better understanding of how I want to draw that stuff when I get closer to it's release. Individual pages are storyboarded with pictures. I find it easy to write in the individual pages as I'm drawing them. Finally, there's a lot of major events that will occur over the course of the comic but, admittedly, that stuff is pretty strictly in my head. I don't know if it's sensible to have it up there instead of on paper but it's the way I'm used to doing it.
