Timelapse Drawing: Sight Size Drawing "Cartoon" for transfer

This is how I draw a "cartoon" or preliminary drawing for a painting. I then transfer this drawing to the canvas. THE MORE TIME YOU SPEND AT THE BEGINNING BEING SLOW AND DELIBERATE AND CHECKING YOURSELF, the less time it will take overall.

If you are referencing this for bargue drawing - normally we would push the linear portion of this drawing further and then when we fill in the shadow shapes we fill them all the way in, and in one solid mass.

Real time about 2 hours (this is obviously sped up!)

Process:
start with a single vertical plumb
begin with singular clear lines for large proportions and things that are easy to see
use straight lines
keep your pencil SHARP, sharpen often
STAY SIMPLE
constantly check yourself with measurements, alignments, etc
start to build additional marks off of the simplified double-checked marks
add additional information in stages, building up to complexity (we call this articulation)
max out what you can find with line
stay straight line-y and structural as long as possible
continue to correct and assess as you go
SLOW DOWN
when you have maxed out what you can do with line, filling in shadow shapes with a solid value can help you to see additional adjustments
