This was a request from (https://www.deviantart.com/gesztenyetorta) who had the good luck/timing of asking for an MLP pic while I was wanting to do just that.  
She asked for her OC Chestnut Cake (fav.me/dbphqlh) as a ninja with a katana… and that’s it. So not having a lot to go off of I needed a scenario and figured fighting one of those vines from “Princess Twilight Sparkle” was a good enough scenario. It also gave me a way to make her outfit, which I based off her hair bows and cutie mark, really pop. Unfortunately, though I couldn’t get the rest of the colors to balance out as well as I wanted but it’s not too bad.  
I don’t own this character just the pic
