Sharingan Triangle

This is a Sharingan Triangle, as I like to call it, I was drawing a Sharingan eye (anime, Naruto) and I just altered it into a star/triangle shape. This appears in a fanfiction i'm currently writing (not posted yet but will place the link later) as a tattoo to represent loyalty to a certain clan, the Uchihas'.
Both Sakura and Aome have this tattoo.
