Okay, this is something that I hope will help some people.

Every artist (and writer) wanting to break into comics needs to have sequentials in their portfolio. I don't give a rat's pimpled heinie who you are, you can't make a living just doing covers. Alex Ross doesn't, and Adam Hughes...well he does, but he started on sequentials, so don't gimme no lip. Here are links to some sample scripts you can work off of ( and for writers to look at so you can see how the bigger..well any companies might like to see your scripts written)

Ryan Scott Ottney. Good stuff, Batman Beyond, Batman, and an EXTREMELY funny MArvel S&M script involving Joe Quesada adn Kevin SMith. I hope for good thigns in this guys future.
