Firstly this here is the actual page from the book containing the illustration you are getting worked up about:

Notice the underlined parts ? Loomis himself was a very very well trained illustrator. He knew exactly what the media of his times demanded from an artist and he followed those rules just like we all do. Thats called being a professional. That you actually chose his work as your model for 'reality' is really quite amusing...

Secondly I am sorry to say this, but you are a very typical example of an engineer posing as artist i see occasionally. The same sort of people who draw up facial feature 'maps' or spend years collecting stat data on beautiful people trying to reduce beauty to mathematical formulas. Sorry mate it doesn't work that way... yes there are so called 'laws' of proportions, but they are 'laws' in the artistic sense, not absolute numbers that every one must follow. In fact they are not even terribly accurate in a real medical sense, but since they help the average artist to work from a firm footing, we fudge over the details and let em stand. They are meant to be a base to build on, not the kind of absolute gospel truth you are getting blue in the face about.

The only real guide to life is LIFE, not your own silly ideas of what it 'should' be.
