Rob -
Are you hoping to make it to one of the larger companies, like Marvel?
I've got a couple graphic novels plotted out using photos, based in the world of Obsidian, and I've got about a third of the pics I need, but I never have time to work on them! We ended up using a bunch of the pictures as cutouts in the playtest materials my friends and I put together for the live action version of Obsidian (you can see them here
http://www.twilight-games.com/obsidian.shtml), but I never have time to work on my own projects, so I don't know that I'll ever finish them. I figure as long as I have fun working on them, it doesn't really matter if they're ever done.
Do you have any already finished?
