New Story idea give me your opinon

Sin City Chronicles: Equestria

Sin City. Home of the seven story tower also known as the home of the Seven Deadly Sins Wrath, Greed, Envy, Pride, Lust, Gluttony, and Sloth. They rule the city enforcing their sphere of influence...that's were the group called the Virtues come in. The Virtues are a group of people of any ages or genders that embody the long sence departed virtues of humanity: Trust, Justice, Vengance, Peace, Vigor, Love, Friendship, and Valor. They are the city's only hope, but with the recent death of their leader Valor they flock out to find his reincarnation, and bring them to the order. This reincarnation is Noah Issacs. A normal teenage kid with a strong sence of, you guesed it, valor...not enough to govern his life though he is still mischievous. After a few days travel he arrives, and meets the current leader Friendship...she has purple skin, and bacon pattern hair...her name...Twilight Sparkle.
Art is not mine I found it on the internet, and I'm pretty sure the idea is original...I hope.
