It's because they all have the same jaw/face template I think.
The reason they're weird to me is the bottom part of their face is too gray. I know it's supposed to be a bit more gray/blue than the rest of the face but this is too much, they look like they have 5 o' clock shadow. But still it's obvious someone put a lot of effort into this so I can't really say anything bad.
Could we post dolls from dress-up games too? I like dress up games more than avatar maker games
