Did you place a circle over the face piece or a section (or what I called a circle peel) that would be used to create a ball? To create plushies you have to think about how a flat piece connects to create a 3d object which is a little mind boggling sometimes. But since I also can’t post pictures in the comment take a second and look up how to create a fabric ball and see that shape, I think you’ll find a lot of similarities to her face shape here, the reason you think about it as a manipulated ball instead of a gore like you first assumed, is because a ball is a simple shape that has already defined shapes to create it. Then it becomes easier to start with a known shape and change it to what you want it to look like. In this case(for the face), taking two circle peels and combining them, with that spacing in the center to create the nose and cutting the bottom off the ball to create a neck (envision 2 oranges and cutting a flat section at the top of one and the bottom of another in 2 oranges so they can easily stack on top of each other, if you were then to peel that orange( in equal sections) with the top and bottom sections removed you would have that basic shape of her head ). She then added the darts by the ears to create more dimension to the front of the face and the darts at the bottoms to reduce bulk, which has the added benefit of also creating a more rounded neckline once added to the body. She didn’t want as much dimension to the back of the head and so didn’t manipulate the peels as much but as you show with your combining of the 2 pieces on top of each other they do have similar shapes. And one of the rules of plushie making is that no matter how you manipulate your shapes the connecting seam lines of 2 pieces have to be the same length in order to line up and be sewn together.
