IME, most of the characters possess one or more of the following traits: brown hair, Human, male and Fighter class.
That's because paladins are not available yet...
I just don't think social media is a good reflection of what most players choose, it's rather a reflection of what is popular on social media. E.g. if you look at that Astarion seems a beloved character, whereas I would not be surprised if he was actually the most disliked & killed companion.
People like things that are attractive, including faces. You could almost say that people are *attracted* to those types of things.
It's not social media; it's human nature. For the most part, people are going to choose the faces that are attractive. Occasionally, there'll be some other choices, sure, but those will typically be made because of flavor or humor.
Personally, I find a lack of attractive human faces all around, but especially in the male category.
