General: half-closed eyes
Images or animations in which a character has both of eyes somewhat, but not entirely, closed. Note that this isn't necessarily suggestive at all. Characters may simply be about to sleep, feel extremely angry, et cetera.
- eyes_closed - when both eyes are closed.
- one eye closed - when only one eye is closed (unintentionally).
- wink - when a character is intentionally closing one eye.
