This is awesome and simple at the same time. Good job! To you and the model. I love how the cosplayer brought out the purple and the blue. Next time, you could bring out the pink as well, but not have it overpowered. You might even want to include the lavender. If you want, you could make a pair of pony ears (and horn), and make that out of Model Magic or similar. Wings, optional, but, just do whatever you want to make it. Otherwise, nice photo, nice cosplay, it's very well done. Kudos to you and the cosplayer that did this. You both did a very awesome job!
