This is what I ended up with. Started over three times until I got a block-in I was satisfied with to render. Sometimes it's hard to see whats wrong but you know something is. Need to get up and take breaks more.

I tried pushing the dark values a bit further than I usually do. It was a struggle to keep them all balanced and even. The pinky fingernail trick to keep the hand off the page while still maintaining contact is a great tip!

Unfortunately the charcoal pencil I have did not give me very dark marks. Hopefully this light drawing still works.

Really benefiting from this shape to shape way of drawing! I always struggled with female heads when using the Loomis or Reilly lay in. Thanks so much! Would love to hear which areas you see where I may still be going astray here.

It may be due to the camera angle but, when I use your suggestion of rapidly comparing your drawing to its reference, I see the drawing as being slightly stretched vertically compared to its reference. Are you seeing that too on the video? When I was a student, this type of distortion was a common issue for those of us who didn't begin a drawing with an envelope that established the overall proportions of the image. What are your thoughts about using measured envelopes as a beginning, as Raphael Ellender teaches in his book, Basic Drawing? BTW, Andrew Loomis offers a "visual survey" on page 88 of, Figure Drawing For All It's Worth, that's kind of similar to your "inside to outside" method of measuring.
