Cover options

So I'm going to be participating in Keba Si Rota's 2015 Sketch marathon And I'm having a hard time deciding which of my O.C's are going to be on the cover for the comic the sketches will go in.

Here's a list of some of the one's I was thinking for going on the cover. Can everyone please tell me who you would like to see on the cover. I want to get the cover done and up before the new year.
