Well it would've been a bit boring and a lot less chaotic if everyone had the same image of her.
In my case, this is how Eris looks to me.
To some she may seem like a granny-on-nitro, with a blowtorch and a permanent PMS problem.
Personally i think a godess like Eris has her vanitiy and would rather appear as a lush young woman
Since its a 3D model i can add wrinkels at will if you want a personalized version ^^.
(just don't complain at my door when she feels offended and comes down on you scorned)
