The one difference between comics and, say, cinema or prose, is that you've only got so many pages, and publishers will work to a set page count. So you have to work out how many pages you actually have and how much to allow for each story.
Comics have the page as their real estate so you've only got that space to tell the story on. But the other thing only comics do is to have the words and pictures being simultaneous. Your brain is flicking between them and you can put in some excellent narrative devices; you can off-set things and juxtapose things between word and image.
Lovecraft gives me the pip as he uses so much description that needs heavily condensing.
