My submission for a contest hosted by ask-princesssparkle on Tumblr. (link)
A Ponyvillian, who happens to remember me, suggested that I should participate in this armor design contest. Although I'm already very busy watching over Tryp and the Hunters, I managed to quickly come up with a simple, functional design that I hope the young princess will like.
Dear Rarity, Please find enclosed a proposal for the barding to be worn by officers of the Royal Guard assigned to Princess Twilight Sparkle. If you can find me in the future, you're free to let me know what you think.
The wearer's mane is pulled through the top slot of the helmet. Holes for horns and wings can be cut into the helmet and back armor, respectively. The armor is composed of a durable steel alloy. Blue stripes along the helmet and back armor and a 6-spoke gem embedded in the chest plate designate the wearer as an officer assigned to Princess Twilight Sparkle.
