While people considered me a good drawer since I was a child, I remember just repeating either similar detailed drawings I drew before, or otherwise just taking plenty of time to draw. I believe anyone with time and patience can make a nice drawing of a scene.
The "free drawing" class had no rules or lectures: you brought the materials you wanted to work with (some brought ink, others pencils, while I brought charcoal). The only thing determined was the timing between poses for the model: for each session the first few poses were very short (say a minute), and then the pose durations would progressively lengthen until say 5 minute poses. At all times you were free to tear your picture up and retry drawing the pose again.
My drawing skills improved considerably. The short "warmups" actually force you to get proportions and outlines correct on the first tries. Conventional wisdom says haste makes waste, but when learning or refining skills, it seems natural selection has hardcoded the sensation of haste as a stressor prompting attention and learning.
I am convinced I could have drawn similar quality drawings before enrolling in those classes, except they would have taken me easily 5 or 10 x as long to draw. Being forced not to beat around the bush and feeling the penalty of making a hasty mistake (further decreasing time left for the second try in the remaining time) does seem to work.
My only gripe is that the technique is termed "Consistency" whereas I would reserve such a term for an improvement in performance not inference speed, although I understand that they indicate "consistency with what would ultimately have been generated one token at a time". I would rather dub it "Proficiency LLM", where the same output is expected, only without the inhibition of stuttering to the same conclusion.
