Those are female characters. They just don't have ridiculously large gamer B008$. And lack the fan service bikini armor. So, actually, Valheim is ahead of the curve in those aspects. Dress a male character and a female character in the basic leather armor and you can tell the difference in shoulders and hips, although it's more subtle than gamers are used to seeing.

Honestly the character creator in general is not that great. But once you're in armor and wearing a cloak it ceases to make any difference.
