I went as Discord to Bronycon 2012, with my sister ~cyclone91 who went as Twilight Sparkle/Chysalis disguised as Cadence. She helped with all the sewing/making the claw out of antique leather glove and claws, I gathered the materials for the whole outfit together and created the antlers using a real antler and melted wax for the other one/painted them with oils. Its a pity you cannot see the rest of the costume here, but more uploads soon should show it better off. We had a lot of fun, we even got to be in the costume contest and the Brony documentary, it was so cool to see so many creative people together in one place! Btw in case you can't see it, my nametag which was purposely written on upside down says 'John Luke Picard'...cos, yknow, Q and all...John Delancie...yeah. I'm an uber-dork now, aren't I?
UPDATE: Btw, I also made a pair of genuine Kaa-style hypnotism eyes for this costume as well. They were very cool in my opinion, and believe it or not completely see-thru. But due to self-conciousness, and better visibilty needs in dim lighting and crowds, I decided to forgo them. I actually wore them a few times for a short while hidden under the glasses you see here, so I could get the special opportunity maybe to 'flash' a person taking my picture or a friend. But then I realized just how many news crews were strutting around, and I decided I already looked goofy enough. My fears were not unwarranted. This photo has poor resolution quality, because it was one of a couple images that actually landed in an online article of Newsday.
