Preparing for Halloween (Patreon)

So, its time of the year for me to get ready for the 13 Nights of Halloween image set. Because I work at a haunted house in October, I dont have the time to make all the images during October, so I let to get them done a month ahead. But everywhere I run into a theme problem. So I'm letting my patreons decide between the themes. So I'll have a poll this week and then week I'll open up a suggestion board for people to recommend an overall story theme that ties all the images together. I hope you'll take the time to suggest something. 

But first, this poll, simple. Which would you rather see, 13 Fan art or 13 Original Characters?
