Good Trait, or Bad Trait For My Vampires?

I am writing a vampire novel called "Tainted Pages". Well, the trait for all vampires in my book, are outrasgeously colored eyes. Well, um, like, UGH, I don't really know how to explain it to you. Well Milo's eyes are turquoise with black swirls. the number of swirls in the eyes, marks how old they r to other vampires. like when you saw the trunk of a tree off, and look at the rings in the stump. Tell meh, what u guys think about it lolz. :D
