So I haven't made any pages yet but If I can make more suggestions...
1 - Try to post full images, big enough for people to see. Example. Posting sneak peaks of the graphic novel is a great idea but when clicked it just links back to the main site. The way I see it as long as it's a preview page or snippet of a page and not the full product you can post it on the wiki. Cause to be honest I as well as other possible visitors would like to see them full size.
2 - Character pages. There is a format for these kinds of pages but it's a bit difficult to do. But yeah character pages would be a good idea. Plus maybe we can add more to the character's backstory that we've yet to see in the comics.
Other than that it's starting out ok.
