Faces?

I'm not sure guys...
Story time:
I was sitting in math class being bored out of my mind and I think to myself: "I wanna draw some circles." So I did. Later in math class I was bored and also desperate to be doing something else and so I drew the emotions I was feeling inside of the circles. Ever since then I've been obsessed with drawing these. I literally have three pages full of them.
What do I call them?
I mean they're pretty much just emojis...
Hope you have a good rest of your day.
