The sphere and the turning line
A circle for the cranium and, over it, the centre line curving to the left. Curved, never straight.

Three-quarter is the angle manga uses most, and the one that fights back hardest. The whole trick is one idea: the far side of the face compresses. Accept that, curve the centre line instead of drawing it straight, and the rest follows.

The first one is here in full. You follow the rest inside the app, with the plate full size and the voice that explains it.

The other steps, the voice that walks you through them, and the feedback on your drawing are inside the app. Creating the account is free and asks for no card.
An AI compares your drawing with the plate and tells you what to fix. It is not a person looking at your sketchbook.
