You people forget that comics are 50% pictures. Without the visual part, they would be merely text. I believe art plays an important roll here, far more important than some of you may think. ATturtle makes a good point, but forgets that the comics we read today started from nothing, built up and made a name for themselves in their own unique way. This, however, is a contest, a contest hosted by a major pop culture related website, the very fact that they offer a paid contract to the winner means that they will want some profit out of this as well.
Art and ambitions are nice and all, but in the final final hour, all shall serve the one...true...king. (by ''king'' I mean profit, sorry couldn't resist the refference).
You might accuse me of being very cynical and heartless, but this attitude and view on life is what helped me write my own submissions (also, the artist pretty much edited 60% of my scripts). ...I am crap.
