I decided to actually try and use these in The Sims, and I will be making them into an eye pack for the game. Below is a link to a very early version. They will be looking a lot different than the picture above, because Sims is not an anime game at all.
I will be naming the pack something like 'Xoriu Sphera anime eyes' or along those lines. I hope that's okay by you. I will of course be linking to your page as well, whenever I upload the pack. But for now they will only be for personal use, until I'm completely done with them. And there's a lot of colours to chose from!
And as promised, a link to a screenshot:
