And when I mean "practice", I mean I just found a random facial expression reference on Google and then tried to recreate some of its facial expressions, giving the most similar vibe possible, in my art style.

I end up not liking just 2 facial expressions, I think. Which I honestly found it rather confusing.

I'm kinda glad I tried this out, because I wanted to learn some more exaggerated facial expressions (for the funny). I can't tell if I truly learned how to actually draw these facial expressions, but at least I have a basis if I ever need.
