I drew the Chimpanzee a bunch and then a few skulls and the skeletal layout from memory. Then I moved on to the Gorilla which was observation only.

I ended up throwing some more human characteristics on this Chimpanzopus. Not super happy with the face or many of the details, but he is fairly dynamic I think. I would have continued him, but I wanted to move on and learn more.

Took some humility to draw cylinders for an hour but glad I did it. Very good practice and helps a lot with making the perspective intuitive. I feel like I restricted my notional vanishing points to the scope of the page, and I realize now that if I had expanded the horizon line beyond the page I could have created a greater variety of perspectives.
