It's cute, fashionable, adorable, dandy, original and 1337 at the same time. This is really a good deviation for making your OC the fourth member of the Cutie Mark Crusaders.
I am a brony and i really think that you're OC should really be in a contest sponsored by The Hub which is only if you're a deviant. Whoever wins the contest, the OC will be in the show and then it would be history to the internet and also television.
For the record, i am really satisified with the whole cute stuff. I am brony just because of the cuteness and stuff. Oh and normally it looked like Kia from Freddy vs. Jason. But overall, it looked cute.
