Flatheads and the Half-Sphere Higher Torus Portal

Flatheads. I'm reusing images A, B and C, and a new image D, which is nicely illustrating that the higher torus can seem like a 'half-sphere' when it is the portal that crosses/straddles the barrier into a higher-density-reality torus.

When the body-torus has a head-torus symbol that is missing the rounded top of the head, I think that's equivalent. Eyebrows are a barrier symbol, and/or a headband can serve as the barrier symbol that goes half-way through a portal torus.

I started a new collection of half-heads yesterday, so you can see more examples and wonder, why is this artwork missing the top of the head? https://ca.pinterest.com/stevenbhalls/half-head/
