Yes, the smile is powerful. So powerful, in fact, that it can convince the mind to start releasing feel-good dopamine! I'm not much into mass media, but there's some truth in this article.

I've really enjoyed these drawings of yours. You've captured the authenticity of the smiles so well. I've always struggled with that as an artist, so I've focused on hands. I've always loved sketching hands. You can tell a lot about a person by their hands. Not as much as their faces, but still quite a bit. 😉
