While I haven't been able to practice all the elements I listed out last night, I have done as much as I wanted to following my personal interest.
Tomorrow will be focused on doing perspectives, shadows and background work. If there is time, also action poses!
In terms of time investment, since drawing requires intense focus, I have only been able to work on it for 2-3 hours a day so far. Partly because I feel I'd still be able to draw caricatures on Saturday with the current pace, so there isn't more incentive to push further. Another bigger reason is my back pain, but also a great motivation to create a very balanced schedule and take care of my health.
Below are today's practice work on hands, feet and human body, particularly proportion. The guideline circles are AMAZING, which I've left visible on the screenshots.
