That's interesting, but the way their business is built, it relies on you being either or. Someone might correct me on this.
As far as I can tell, if it's more visual - post it as a comic. If it's more wordsmithing, with illustrations and art as a factor of enhancement, then post it as a novel.
Turbulent March by @Berserker is a great example of the latter.
But yes. Pitching to comics does have a 2,000 subscriber barrier, which you'll have to breach to even be considered. Hope this helps.
