How did they do eye placement in Pinkfong characters

I love love love this style. I also am horrible at placing eyes inside of a head for some reason. Can someone please explain to me how they got such a shallow arc (not a bulging eye ball) for these characters? Also, if feels like it’s resting in the skin if that makes sense.

I am basically brand new and it would help me so much.

An even bigger ask would be if someone could record a video of them doing it so I can watch along.

Thanks for everything!
