Heterochromia cc?

Moonskin93 did have some. If you google her name you should find her tmblr. It can be somewhat explicit and language can be a bit confronting but she's tamed it down a lot from what it was. And it's hard to find her stuff on the tmblr and some of the links didn't work last time I checked but her work is fun, different and interesting.

I only did a quick search and found these so there could be more out there.

ChazyBazzy has some heterochromia eyes too. https://chazybazzy.tumblr.com/tagged/Mesh%3A-EA-Eyes

Thanks everyone. I got all of them and I'll see which ones I like when I go back in to my game later.
