Could anyone perhaps help me add a cutie mark to my OC character, Twila Starshimmer?

I used GeneralZoi's Pony Generator--found here http://generalzoi.deviantart.com/art/Pony-Creator-Full-Version-254295904--over at DeviantArt, and there's an "import cutie mark" button, but I need help finding a cutie mark and also getting it to show up!
