I haven't seen any yet and there doesn't seem to be appropriate category (unless they go under makeup).

No, unfortunately basic facial features aren't allowed as CWs. Things like fake lashes and blushes are, though. Fullbody items (think of the latex) / fullbody mods aren't allowed as well.

I think it's pretty much because you can't change how the base looks (even if removing eyes is a feature now), anything like tattoos or facial features/changes to the HA aren't allowed unless the tattoos are part of a different item or something.

That's why for the peka-boo event they picked more winners than originally planned so that those who put out eyes and lips could have a chance of getting their items on site. They did say they might have more artist competitions like that, so those are probably the times when people will be able to draw those kinds of modifications and maybe get accepted.

Ah, I see, thanks.
