Trying to understand the Loomis head

I think today I kinda figured it out from the side view. it is still not perfect and I am still a little unsure about some elements, but I think I got the basics. And if I have to go quickly I still throw everything I learned over board. From the front I am still struggling. Especially with the chin section. I think my heads turn out a little too "short" or way too long. And also to wide or to round. I am not happy with it. I am going to look more into this. :) And of course practice!
