"waving at you" should imply "waving" and "looking at you"

waving at you → waving & looking at you

Not actually sure about the second implication, but there might be few enough instances where the character isn’t looking at the audience (eyes closed, usually) that having looking at you removed after upload when relevant is the safer bet.

But the important implication here is waving.

The not totally sure about the latter implication, but waving added.
