[Quiet Man Cometh]

Never tried a comic book approach but I've thought about it for a couple stories I have. Basically, I picture a particular panel, or more than one, and work around that. I do find that I need to take care of one thing (ie the story) before the other (the art) or I get overwhelmed trying to juggle both. I have some stories where I didn't get past one or two significal panel as far as the art part went, then tossed it and went with the written story instead which, by the way, is still unfinished. I think adapting a written story to a comic can be tricky. If you are starting something original, maybe consider thinking of it in pictures rather thatn in narrative. Comics books are about using image to show content rather than words.
