Head on over to the The Big Under Cover Art contest! You can use art that you made for submissions to this group in putting together a submission for the cover of the actual digital comic. Here is the link: http://news.deviantart.com/article/137706/
Also, in a few months, we will be putting together a different fan art version of the comic right here on deviantART that will stay only in this Group. Watch for it!
Good luck!
