I tried another approach to drawing the cougar. Of course, it will be worse first, but I hope it will get better, much better when I grasped the principles of this new approach. The idea is how do the forces run through the body, and how can I express that through lines?
I also made a time-lapse video of me drawing the sketch. I first did it in blue line fine-liner, and drew the final lines in black pencil lead.
That is all.
