Uh, it's a hard question to answer. I tend to balance both the personalities of the Pony and the Knight she shares the zodiac with, for example this one:Starlight began her arch like a tyrant trying to enslave the ponies of her village under a promise of false equality. Capricorn shura in the other hand, while not being a tyrant, he was very saddistic, trying to kill the bronze saints in defense of Athena's sanctuary, and was the main responsible for the death of Sagittarius Aiolos when he tought the sagittarius saint betrayed the goddess Athena. So, both Starlight and shura thought they were doing the correct thing, but soon they saw they were wrong, and tried to correct things. (Granted, unlike Shura, Starlight did not have to redeem herself by dying xD).But that's not all i take into an account when deciding which cloth to give each pony: i also pay atention to the common perception of the Zodiacs (as in the real horoscopes). Capricorns, are ambitious and determined, and won't stop at nothing to achieve their goals, and are very cold-minded to achieve those goals. After her defeat at the village, Starlight commited herself to perfect the time travel spell from Starswhirl the Bearded, a very hard task to make, and she did it, and not even Twilight could defeat her, that's why i thought Capricorn was a perfect choice for Starlight: by her nature and the story arch she shares with Saint Seiya's Capricorn Shura.And nah, i do not take the cuttiemarks or elements of harmony into consideration to place the ponies under certain zodiac, that would restrict my criteria by a whole lot.I hope i anwsered your doubts.
