As a Twilight cosplayer, I can't recommend the horn/ears combo enough! While I made my own (didn't think sawing through Yaya's was the best idea just to add lights), the horn makes the immediate connection to you cosplaying a unicorn.
It might also just be the photo, but I also can't see Rarity's cutie mark anywhere on your cosplay? A little applique on the vest would be a very nice detail!
