I actually have examples of my process at hand from my most recent short comic, so I can show you some
For the major story beats I do something like this:
It's mostly just quick doodles of the major events that need to happen to move the story along (or complete it in this case, since it was a short one-off.) I also put some minor event/dialogue notes on these.
For thumbnails, I start with the gestures and move on to panel layouts. My gesture thumbnails consist of pages and pages of this:
And mostly include all the small bits and pieces that I think would enrich the story. Many things get cut and adjusted during this stage.
Finally, before sketching the page drafts, I do a quick sheet of panel layouts that is almost completely incomprehensible and not much more that a brief visual guide for myself. Such as this:
Hope that clears it up a little bit
And no problem for the tag! I read your responses and I'll be commenting soon
