Thank you. You can't become an animator without mastering movement. The samples above I posted are gesture (in other words, pose) drawings from models so the entire premise of the assignment is to draw a gesture and have a sense of movement with minimum detail.
Stuff like this.
It's really fucking hard.
The goal is to be able to pull off these in 10 seconds. The ability to use minimum lines to create expression and know what you're looking at is hard af. The sketches above are from two minute times assignments. The goal is to create a gesture drawing in two minutes. Hard. As. Shit. But it's the same training renaissance painters went through so you kind of are obligated to do it by necessity.
