You're meant to put your paper right close to your cast, which is your reference and step back like six or seven feet and measure, so you walk back and forth, measuring and putting reference points in your paper, until you feel like you have enough reference points to just connect the dots and start working more and more detail into the drawing. You can work as much detail as you want into the drawing, except you have to keep walking back and for over and over again. It's an arduous process, to say the least, but it's a really good observational exercise. It's good to find relationships, points that converge on a single horizontal or vertical line.
I've thought of doing it maybe one more time, just to polish that observational ability, but I don't know if I want to subject myself to that again.
I decided after the third session of work, I think, to just take a fucking picture and take the thing to my studio and work from there, because I was up to my balls of walking back and forth. So, when I started putting on shadows and the ear was basically all drawn, I stopped walking back and forth.
So, my tools were a blending stump, a kneading eraser, an HB pencil and I drew over Canson paper. Whilst I was taking measurements, I was using a knitting needle, and I should have had a plumb line, but fuck that noise. I had enough with the knitting needle.
So here is the final result, I really like it, I'm going to frame it and put it up in my etsy shop, which is called Gabriela Handal Arte, because I have a lot of imagination.
