That face is so cute, I'm sorry I know the point is that people can wear smiles for different reasons, but really you outdid yourself, and this expression is to show not every smile is happy but it is so calming to look at. I think its the angle but really you made Fen come off very welcoming and friendly in this, which I'm willing to bet was the point.
