I wasn't going to update them. But after thinking about them, I could have done them better. Since I will use the kids more, I should update them. Some changes are minor like hair color, eye color, and different poses. One will be major. I won't change all of them. Just one I feel that needs to be changed.

As for the new kids, I'm not going to fully show them until the game comes out. Surge's kid is indeed Sonic's kid.
UPDATE: The Sonic VN has been out long enough. So for those who haven't played the VN (you should play them), here is Surge's kid.
