I'm having a hard time (as usual) with constructing the jawline from
this pose/point of view, but it's the whole point of the pose: it's what
models do all the time, currently. But even as a kid I've tried to draw
this pose and it was never easy. Too many things to do: foreshorten,
how to draw the nostrils right, how to render the chin and jawline. how
to render the bridge of the nose... and all while not copying from a
photo (I'm using references, but not the exact position).
