its my version of humanized Twilight Sparkle.  
While I dont know much about my little ponies and only watched that original when i was 3,I know theres a lot of people that like the new one,i saw an episode it seemed like a cute kids show,not my thing,but i can see why some people would like it.
 
So if i was going to do it,for friends or otherwise since its something im indifferent to,I was going to make it something i like,Keep in mind i only know about twilight sparkle what wikipedia,my friends,and 1 episode said lol that i was going to do it a way i wanted to,i gather mage,smart,mystic from this character and decided to go with an elvan,or fae kin purple themed mage,with the [pony mark as a bindi] i do have ear clippies and a horn I am making to clip in to this wig too so it will be even more complete.
 
the wig its self is my old rider wig,i just bought cheap extensions because i was low on $ for this costume and had to do the best i could for cheap,so there are neon pink and purple highlights in 2 places,just a bit harder to see.
