* Good art. Doesn't have to be spectacular. Just not craptacular. Same with the writing. (This is the most important suggestion since the comic will probably be a comic reader's first impression of CF)

* Keep inside jokes to a minimum or leave them out. Keep plots, stories, etc. simple. Nothing obscure, complex.

* Have a cast of characters. An orc, a dwarf, etc. like in CF.

* Don't mix drama and comedy. Either or. Maybe future RPers will want to see serious stuff, but I'm thinking comedy is a better pick, since that's what alot of people look for when they read a comic.

* Update regularly. Once a week would be grand.

* Host the comic on its own site, but make sure to mix it in with webcomic sites, so it'll get more exposure.
