The two types of eye makeup fill the whole eyes now, so you can use them to color closed eyelids. This was a contest wish by Caribou. I know it is not exactly what you asked for, because I changed the makeup instead of the eyes... but the result should be the same. I prefer to keep the selection of the eyes as simple as possible for now and keep it separated from the make up, so I did it this way.
Would it be possible to keep the old crescent-shaped eye make-up as well as the new ones? The new ones work fine if you actually use the pieces as
eye make-up, but the old shapes were really useful to use in other ways because of their shape - I've seen a lot of pictures where people have used the lower set to give their character large breasts, for example, and I've certainly used them both many times whenever I've needed a random curly-looking bit. I'd hate for one of my contest wishes to limit what people can make with the creator and I think the crescent-shaped pieces would be badly missed by quite a few people.
That said, the new round ones would offer new possiblities for interesting uses as well, so if it's possible to keep both sets (on the same layer, I guess, as an either/or option) then that would be ideal.
