Can someone help me with proportions? I see very different ways of doing people and I'm wondering which is really best.

I see some people using 7 in their art (mainly anime) but loomis recommends stuff like 8 for heroic figures and 7.5 for fashion ones iirc.

I guess another question would be if I really have these correct. Once the head is setup as the basic unit do I then do half the head for the neck or another entire head for the neck + upper torso?

The eyeline of the Loomis head ceases to work because of most anime stylizing them as very large, and with that the rest of the construction lines are thrown off (most importantly bottom of the nose). Loomis is still good for at least drawing the chin and sides of the head for, that’s the most flexible part of the technique.

How am I supposed to go from a circle to even the first step in this? All the other stuff thus far has had some sort of logical beginning step I can build off of, but here I can't make out anything. Anywhere I start I just end up with janky proportions.
